opcodes: Use autoconf to check for `bfd_mips_elf_get_abiflags' in BFD

Fix a regression introduced with commit 5e7fc731f80e ("MIPS/opcodes:
Also set disassembler's ASE flags from ELF structures"), further updated
with commit 4df995c77118 ("MIPS/opcodes: Also set disassembler's ASE
flags from ELF structures"), and use autoconf to check for the presence
of `bfd_mips_elf_get_abiflags' in BFD.

opcodes/
* mips-dis.c (set_default_mips_dis_options): Use
HAVE_BFD_MIPS_ELF_GET_ABIFLAGS rather than BFD64 to guard the
call to `bfd_mips_elf_get_abiflags'.
* configure.ac: Check for `bfd_mips_elf_get_abiflags' in BFD.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add `libbfd.la'.
* aclocal.m4: Regenerate.
* configure: Regenerate.
* config.in: Regenerate.
* Makefile.in: Regenerate.

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.

* linker.c (generic_link_check_archive_element): Call target
bfd_link_add_symbols to add element symbols.

Remove "collect" forms of generic linker add symbols functions

Nothing calls them and they were in the way of a bug fix.

[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
    msp430-sim/-mhwmult=f5series

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.

Do not add padding if an output section is marked as ignored

* ldlang.c (size_input_section): Avoid calling insert_pad
if output_section_statement->ignored is set.

bfd: aarch64: fix word and arrdess size declaration in ilp32 mode

ILP32 has 32-bit word and address, but currently they declared as 64-bit in
bfd_aarch64_arch_ilp32, which breaks further logic of bfd. This patch fixes it.

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains

Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).

Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

MIPS16/opcodes: Respect ISA and ASE in disassembly

Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.

To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate.  Adjust the single

In assembly disallow size enforcement suffixes as appropriate: `.t' for

Re-work RISC-V gas flags: now we just support -mabi and -march

We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI.  We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.

Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive.  Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.

This patch implements these two new flags and removes the old flags that
could conflict with these.  There wasn't a RISC-V release before, so we
want to just support a clean flag set.

Rework RISC-V relocations

Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them.  This patch
significantly reworks how we handle linker relaxations:

 * DWARF is now properly supported

 * There is a ".option norelax" to disable relaxations, for when users
   write assembly that can't be relaxed (if it's to be later patched up,
   for example).

 * There is an additional _RELAX relocation that specifies when previous
   relocations can be relaxed.

We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations

  https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md

but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).

Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!

ld: aarch64: fix TLS relaxation where TCB_SIZE is used

TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl   __tls_get_addr => add R0, R0, TCB_SIZE

But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);

Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.

The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);

But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.

Fix edge cases in orphan section placement.

There were still some cases I found where orphan section placement
was screwy -- where the script has no output section description for
either .data or .bss, a .bss orphan section ends up getting placed
before the .data section. In addition, if there is an output section
description for a data section not named .data (e.g., .rela.dyn),
the orphan .bss gets placed before it. This patch cleans that up,
by tracking the last allocated section even as we're adding orphans.

I've also improved segment layout in the absence of a PHDRS clause.
A zero-length NOBITS section will no longer force a new segment
when followed by a PROGBITS section.

HPPA64 needs to add a DT_PHDR header for shared libs.  That's fine

Don't fudge p_vaddr when PHDR in segment

RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite

probably doesn't matter too much since RX is an embedded target, but
it's easy to stop some of the fudges in order to reduce special cases
