Fix an internal error on writing pieced value

In ee40d8d (Move computed value's frame id to piece_closure), I only
updated read_pieced_value to use frame_id from piece_closure, but
forgot to update write_pieced_value, so it causes the following
internal error on arm-linux,

bfd: alpha: Fix crash caused by double free with --no-keep-memory

Without this, ld has been seen to crash in libc when freeing tsec_free:

*** Error in `/usr/bin/ld': double free or corruption (!prev): 0x0000000120ceb6a0 ***

_bfd_elf_link_read_relocs will always return the cached value if
present, even if keep_memory is false, therefore setting tsec_free to
NULL only when keep_memory is true is not sufficient.

Run more ld tests when not native

Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only.  Even
when a test needs to run, it's good to compile and link to exercise
the linker.  So that's what this patch does.  I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup.  It's
much simpler to just link with $CC.

This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures.  If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.

Return 'int' rather than 'unsigned short' in avrdis_opcode

avrdis_opcode return type is unsigned short, but -1 at the end of
this function is returned.  Additionally, print_insn_avr doesn't
handle when -1 (in case of memory error) is returned from
avrdis_opcode.

This patch changes avrdis_opcode returning int indicating the error,
and adds a new argument for instruction we got on success.  The
opcode is 16-bit, so I change local variables type to uint16_t,
and include "bfd_stdint.h" as a result.  On memory error,
print_insn_avr returns -1, which is a common convention among most
of print_insn_$ARCH functions.

link_hash_copy_indirect and symbol flags

A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among
other things, modified _bfd_elf_link_hash_copy_indirect to not copy
ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt
and pointer_equality_needed when setting up an indirect non-versioned
symbol pointing to a non-default versioned symbol.  I didn't notice at
the time, but the pr18720 testcase fails on hppa-linux with
"internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933
in elf32_hppa_relocate_section".

Now hppa-linux creates entries in the plt even for local functions, if
they are referenced using plabel (function pointer) relocations.   So
needs_plt is set for foo when processing pr18720a.o.  When the aliases
in pr28720b.o are processed, we get an indirection from foo to
foo@FOO, but don't copy needs_plt.  Since foo@FOO is the "real" symbol
that is used after that point, no plt entry is made for foo and we
bomb when relocating the plabel.

As shown by the hppa-linux scenario, needs_plt should be copied even
for non-default versioned symbols.  I believe all of the others ought
to be copied too, with the exception of ref_dynamic.  Not copying
ref_dynamic is right because if a shared lib references "foo" it
should not be satisfied by any non-default version "foo@FOO".

dynrelro section for read-only dynamic symbols copied into executable

Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

MIPS16: Add ASMACRO instruction support

Add ASMACRO instruction support as per the MIPS16e ASE architecture
specifications [1][2], completing MIPS16e instruction set support.

MIPS16: Simplify extended operand handling

Simplify extended operand handling and only specially process immediates
which require bit shuffling, using the generic operand insertion and
extraction handlers for the '<' (5-bit shift amount) operand code in
particular.  Require the least significant bit of all extended operand
forms to be (artificially) set to 0 for their special processing to
trigger.

extended operands.
* mips16-opc.c (decode_mips16_operand): Switch the extended
form of the `<' operand type to LSB position 22.

MIPS16/GAS: Clean up invalid unextended operand handling

Bail out right away when an unextended instruction encoding is required
either with the use of a `.t' suffix or by means of `.set noautoextend',
however an operand supplied requires the extended instruction form to be
used.

This is to avoid messing up with the internal state of the assembler,
even though no actual failures are known to happen as a result.  Add
test cases for the situation concerned.

gas/
* config/tc-mips.c (match_mips16_insn): Don't update
`forced_insn_length' or the instruction opcode if an operand

* testsuite/gas/mips/mips.exp: Run the new tests.

MIPS16: Reassign `0' and `4' operand codes

Replace `0' and `4' operand codes with `.' and `F' respectively to free
up the `0'-`4' consecutive range.  No functional change.

gas/
* config/tc-mips.c (mips16_macro_build): Replace `0' and `4'
operand codes with `.' and `F' respectively.
(mips16_macro): Likewise.

include/
* opcode/mips.h: Replace `0' and `4' operand codes with `.' and
`F' respectively.

opcodes/
* mips16-opc.c (decode_mips16_operand): Replace `0' and `4'
operand codes with `.' and `F' respectively.
(mips16_opcodes): Likewise.

MIPS16: Handle non-extensible instructions correctly

Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.

According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].

Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Remove "extended" BREAK/SDBBP handling

Remove special casing for the `6' operand code used for the embedded
trap code of the BREAK and the SDBBP instructions to support supposedly
extended forms of these instructions.

According to all versions of the MIPS16 ASE specifications these
instructions are not extensible [1][2][3][4][5][7][8][10][11], and as
from revision 2.50 of the MIPS16e ASE specifications it has been further
clarified what was previously implied, that non-extesiable instructions
when preceded with an EXTEND prefix must cause a Reserved Instruction
exception [5][6][9][10].

Therefore supposedly extended BREAK and SDBBP instructions do not serve
their purpose anymore as they do not cause a Bp and a Debug exception
respectively and supporting these forms in disassembly only causes
confusion.

the next regular MIPS16 instruction and therefore swapping it with a

Fix more cases of improper test names

I noticed more occurrences of improper test names. The rather mechanical,
tedious and large patch below addresses, hopefully, most of the leftover cases.

As usual, another pair of eyes is welcome to check if missed something or did
an invalid substitution.

This patch also fixes the prepare_for_testing calls to pass proper test names.

[msp430] Sync tc-msp430.c with devices.csv

This patch syncs the generated data structure in tc-msp430.c with the
latest version of devices.csv released by TI.

My understanding is that the devices being removed were "invalid spins",
so can't be being used by anyone, and never will be. Current web
searches related to these devices return no relevant results.

Built and tested (no regressions) as follows:
  Configured with: --target=msp430-elf --disable-gdb
  Test variations:
    msp430-sim/-mcpu=msp430
    msp430-sim/-mcpu=msp430x
    msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either
    msp430-sim/-mhwmult=none

Fix placement of forced local symbols in the dynamic symbol table.

Gold was not placing forced-local symbols (e.g., hidden visibility)
at the front of the dynamic symbol table, or including them in the
count of local symbols recorded in the .dynsym section's sh_info field.

Fix problem where version script causes predefined hidden symbol to be defined twice.

When creating a predefined hidden symbol like _GLOBAL_OFFSET_TABLE_, gold
was incorrectly letting a version script add a version to the symbol,
resulting in two copies of the symbol, both STB_LOCAL, but one of which
was grouped in the globals part of the symbol table.

Class-ify ui_out

This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy.  ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.

In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.

It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

ChangeLog formatting fixes

Support aligning text section from odd addresses

Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd).  Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Resolves https://github.com/riscv/riscv-gnu-toolchain/issues/205

* config/tc-riscv.c (riscv_make_nops): Emit 2-byte NOPs.
(riscv_frag_align_code): Correct frag_align_code arg.

Fix a const-safety issue on GCC-4.9 and above

* config/tc-riscv.c (riscv_pre_output_hook): Remove const from
loc4_frag.

Avoid creating symbol table entries for registers

Instructions like "jal t0, foo" were erroneously creating symbol table
entries for t0 as well as foo, which causes linking problems.  Fix by
reordering instruction alternatives so that t0 is first attempted to
be parsed as a register, rather than as a symbol.

* riscv-opc.c (riscv_opcodes): Reorder jal and call entries.
