Set informational fields in the .shader_functions table.

Also correct the documentation, .scratch_memory_size and .lds_size are
integers.

f4ace63737 AMDGPU: Add target id and code object v4 support
- Add target id support (https://clang.llvm.org/docs/ClangOffloadBundler.html#target-id)
  - Add code object v4 support (https://llvm.org/docs/AMDGPUUsage.html#elf-code-object)
    - Add kernarg_size to kernel descriptor
    - Change trap handler ABI to no longer move queue pointer into s[0:1]
  - Cleanup ELF definitions
    - Add V2, V3, V4 suffixes to make a clear distinction for code object version
    - Consolidate note names

edd675643d [AMDGPU] Emit stack frame size in metadata
Add .shader_functions to pal metadata, which contains the stack frame
size for all non-entry-point functions.

eed6476a87 Reset PAL metadata when AMDGPU traget stream finishes
If the same stream object is used for multiple compiles, the PAL metadata from eariler compilations will leak into later one.  See https://github.com/GPUOpen-Drivers/llpc/issues/882 for how this is happening in LLPC.

No tests were added because multiple compiles will have to happen using the same pass manager, and I do not see a setup for that on the LLVM side.  Let me know if there is a good way to test this.

2327c231d6 [AMDGPU] Do not generate spurious PAL metadata
My previous fix rL356591 "[AMDGPU] Added MsgPack format PAL metadata"
accidentally caused a spurious PAL metadata .note record to be emitted
for any AMDGPU output. That caused failures in the lld test
amdgpu-relocs.s. Fixed.

e7bd52f86e [AMDGPU] Added MsgPack format PAL metadata
Summary:
PAL metadata now supports both the old linear reg=val pairs format and
the new MsgPack format.

The MsgPack format uses YAML as its textual representation. On output to
YAML, a mnemonic name is provided for some hardware registers.

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
