Currently objdump -S is not able to make use files downloaded from debuginfod.
This is due to bfd_find_nearest_line_discriminator being unable to locate any
separate debuginfo files in the debuginfod cache. Additionally objdump lacked
a call to debuginfod_find_source in order to download missing source files.
Fix this by using bfd_find_nearest_line_with_alt instead of
bfd_find_nearest_line_discriminator. Also add a call to
debuginfod_find_source in order to download missing source files.

The AMDGPU HSA OS ABI (code object v3 and above) defines the
NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object
describing, among other things, the kernels present in the code object
and how to call them.
I think it would be useful for readelf to be able to display the content
of those notes. msgpack is a structured format, a bit like JSON, except
not text-based. It is therefore possible to dump the contents in
human-readable form without knowledge of the specific layout of the
note.
Add configury to binutils to optionally check for the msgpack C library
[2]. Add There is a new --with{,out}-msgpack configure flag, and the actual
library lookup is done using pkg-config.
If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks
like:
$ readelf --notes amdgpu-code-object
Displaying notes found in: .note
Owner Data size Description
AMDGPU 0x0000040d NT_AMDGPU_METADATA (code object metadata)

{
".address_space": "global",
".name": "out.coerce",
".offset": 0,
".size": 8,
".value_kind": "global_buffer",
},
<snip>
If msgpack support is disabled, dump the contents as hex, as is done
with notes that are not handled in a special way. This allows one to
decode the contents manually (maybe using a command-line msgpack
decoder) if really needed.

Decode and print the AMDGPU-specific fields of e_flags, as documented
here:
https://llvm.org/docs/AMDGPUUsage.html#header
That is:
- The specific GPU model
- Whether the xnack and sramecc features are enabled
The result looks like:
- Flags: 0x52f
+ Flags: 0x52f, gfx906, xnack any, sramecc any
The flags for the "HSA" OS ABI are properly versioned and documented on
that page. But the NONE, PAL and MESA3D OS ABIs are not well documented
nor versioned. Taking a peek at the LLVM source code, we see that they
encode their flags the same way as HSA v3. For example, for PAL:
https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601

I noticed that, occasionally, dwarf-mode would think that the objdump
subprocess was still running after it had clearly exited. I managed
to reliably reproduce this today and learned that a process sentinel
is not guaranteed to be run with the current buffer set to the process
buffer. This patch fixes the problem.
I've bumped the version number of dwarf-mode.el to make it easier to
install for users who already have an earlier one installed.
I'm checking this in.

Correct issues with INSN2_ALIAS annotation for branch instructions:
- regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for
BEQ/L and BNE/L respectively with the `rs' operand equal to $0,
- microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for
BEQ and BNE respectively with the `rt' operand equal to $0,
- regular MIPS BAL assembly instruction is an idiom for architecture
levels of up to the MIPSr5 ISA and a machine instruction on its own
from the MIPSr6 ISA up.
Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a
new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug:
$ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o
bal.o: file format elf32-tradlittlemips
Disassembly of section .text:
00000000 <foo>:
0: 04110000 0x4110000
...
$
Add test cases accordingly.
