Stephen Tozer 19bb1d5739 [llvm-readobj] Reapply: Improve error message for --string-dump
This is a resubmission of a previous patch that caused test failures,
with the fixes for the relevant tests included.

Fixes bug 40630: https://bugs.llvm.org/show_bug.cgi?id=40630

This patch changes the error message when the section specified by
--string-dump cannot be found by including the name of the section in
the error message and changing the prefix text to not imply that the
file itself was invalid. As part of this change some uses of
std::error_code have been replaced with the llvm Error class to better
encapsulate the error info (rather than passing File strings around),
and the WithColor class replaces string literal error prefixes.

Philip Reames eea989a909 [StackMaps] Add location size to llvm-readobj -stackmap output
The size field of a location can be different for each entry, so it is useful to have this displayed in the output of llvm-readobj -stackmap. Below is an example of how the output would look:

Record ID: 2882400000, instruction offset: 16
   3 locations:
     #1: Constant 1, size: 8
     #2: Constant 2, size: 8
     #3: Constant 3, size: 8
   0 live-outs: [ ]

Thomas Lively fef8de66a6 [WebAssembly] Add DataCount section to object files
Summary:
This ensures that object files will continue to validate as
WebAssembly modules in the presence of bulk memory operations. Engines
that don't support bulk memory operations will not recognize the
DataCount section and will report validation errors, but that's ok
because object files aren't supposed to be run directly anyway.

The majority of the printRelocation and printDynamicRelocation functions

There are a couple of minor differences to do with printing of symbols
without names, but I think these are harmless, and in some cases a small

Tim Renouf d737b551e9 [AMDGPU] Factored PAL metadata handling out into its own class
Summary:
This commit introduces a new AMDGPUPALMetadata class that:
* is inside the AMDGPU target;
* keeps an in-memory representation of PAL metadata;
* provides a method to read the frontend-supplied metadata from LLVM IR;
* provides methods for the asm printer to set metadata items;
* provides methods to write the metadata as a binary blob to put in a
  .note record or as an asm directive;
* provides a method to read the metadata as a binary blob from a .note
  record.

Because llvm-readobj cannot call directly into a target, I had to remove
llvm-readobj's ability to dump PAL metadata, pending a resolution to

James Henderson b41130bedc [llvm-readelf]Don't lose negative-ness of negative addends for no symbol relocations
llvm-readelf prints relocation addends as:

  <symbol value>[+-]<absolute addend>

where [+-] is determined from whether addend is less than zero or not.
However, it does not print the +/- if there is no symbol, which meant
that negative addends became their positive value with no indication
that this had happened. This patch stops the absolute conversion when
addends are negative and there is no associated symbol.

There's no reason to limit the DWARF CFI dumper to EM_386 and EM_X86_64;
ELF files could contain DWARF CFI on almost any platform (even 32-bit ARM;
NetBSD uses DWARF CFI on that platform). So start using the DWARF CFI dumper
unconditionally so that we can dump .eh_frame sections on the remaining ELF
platforms as well as in NetBSD binaries.

Matt Davis 7a24dbdfd3 [llvm-readobj] Print section type values for unknown sections.
Summary:
This patch displays a hexadecimal section value (Elf_Shdr::sh_type) or section-relative offset when printing unknown sections.

Here is a subset of the output (ignoring the fields following "Type" when dumping an ELF's GNU `--section-headers` table).
Section Headers:
```
  [Nr] Name              Type
  [16] android_rel       LOOS+0x1
  [17] android_rela      LOOS+0x2
  [27] unknown           0x1000: <unknown>
  [28] loos              LOOS+0
  [30] hios              VERSYM
  [31] loproc            LOPROC+0
  [33] hiproc            LOPROC+0xFFFFFFF
  [34] louser            LOUSER+0
  [36] hiuser            LOUSER+0x7FFFFFFF
```

As a comparison, the previous output looked something like the above, but with a blank "Type" field:
```
  [Nr] Name              Type
  [27] unknown
  [28] loos
  [30] hios              VERSYM
  [31] loproc
  [33] hiproc
  [34] louser
  [36] hiuser
```
