Don't crash if dwarf_decode_macro_bytes's 'body' is NULL

Hi,

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
      https://bugzilla.redhat.com/show_bug.cgi?id=1708786

During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.

The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3.  This is being taken care of by Mark Wielaard,
here:

  https://bugzilla.redhat.com/show_bug.cgi?id=1708786

However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint.  This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.

OK for master?

GDB (s12z): Improve reliability of the stack unwinder.

Previously, the stack unwinder searched through consecutive bytes for values

This was error prone, because such bytes could also be the operands of other

Fix assertion failure in coerce_unspec_val_to_type

coerce_unspec_val_to_type does:

However, this is only valid for lval_memory.  This patch changes this

Fix GDB build when using --disable-gdbmi

Since commit

    b4be1b064860 ("Fix MI output for multi-location breakpoints")

we get this error when building with --disable-gdbmi:

      CXXLD  gdb
    /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'

This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.

To fix it, use the flags feature of ui_out.  mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3.  Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI.  I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.

cc-with-tweaks: show dwz stderr and verify result

When running the gdb.base/index-cache.exp test case with the
cc-with-dwz-m board, I noticed that the final executable didn't actually
contain a .gnu_debugaltlink section with the name of the external dwz
file:

    $ readelf --debug-dump=links testsuite/outputs/gdb.base/index-cache/index-cache
    * empty *

Running dwz by hand, I realized it's because dwz complains that the
output .debug_info section is empty and fails:

    $ gcc ~/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.c -g3 -O0 -o a && cp a b
    $ dwz -m foo a b
    dwz: foo: .debug_info section not present
    $ echo $?
    1

This is because index-cache.c is trivial (just an empty main) and dwz
doesn't find anything to factor out to the dwz file. [1]

I think that cc-with-tweaks should fail in this scenario: if the user
asks for an external dwz file to be generated (the -m flag), then it
should be an error if cc-with-tweaks doesn't manage to produce an
executable with the proper link to this external dwz file.  Otherwise,
the test runs with a regular non-dwzified executable, which gives a
false sense of security about whether the feature under test works with
dwzified executables.

So this patch adds checks for that after invoking dwz.  It also removes
the 2>&1 to allow the error message to be printed like so:

    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.exp ...
    gdb compile failed, dwz: /home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/index-cache/index-cache.dwz: .debug_info section not present

- In the -m case (multi-file compression), we check if the expected output file
  exists.
- In the -z case (single-file compression), we check if the file
  contents has changed.  This should catch cases where dwz doesn't modify the
  file because it's not worth it.

It was chosen not to check for dwz's exit code, as it is not very
reliable up to dwz 0.12.

With this patch, fewer tests will pass than before with the
cc-with-dwz and cc-with-dwz-m boards, but those were false positives
anyway, as the test ran with regular executables.

[1] Note that dwz has been patched by Tom de Vries to work correctly in
this case, so we can use dwz master to run the test:

...

The problem is that in amd64-tailcall-self.S, CU-relative references are
assigned .debug_info section relative values.  [ This is similar to the
problem fixed by "Fix gdb.arch/amd64-entry-value-paramref.S". ]

Fix this by assigning CU-relative references instead.

Tested on x86_64-linux.

gdb/testsuite/ChangeLog:

2019-05-09  Tom de Vries  <tdevries@suse.de>

* gdb.arch/amd64-tailcall-self.S: Make DW_FORM_ref4 references
CU-relative.

[binutils][aarch64] Add SVE2 tests

Add tests that SVE2 instructions are encoded as they should be, and
tests that invalid instructions have their problems reported.

Also check that each sve2 cryptographic extension is required to use the
corresponding cryptographic instructions.

Finally, test to ensure that sve2 instructions using mnemonics that
exist in sve1 still need the sve2 feature to be used.
