The previous name 'amdgpu_code_object_version', was misleading since
this is really a property of the HSA OS. The new spelling also matches
the asm directive I added in bc82cfb.
Similar to 806761a7629df268c8aed49657aeccffa6bca449.
For IR files without a target triple, -mtriple= specifies the full
target triple while -march= merely sets the architecture part of the
default target triple, leaving a target triple which may not make sense,
e.g. amdgpu-apple-darwin.
Therefore, -march= is error-prone and not recommended for tests without
a target triple. The issue has been benign as we recognize
$unknown-apple-darwin as ELF instead of rejecting it outrightly.
This patch changes AMDGPU tests to not rely on the default
OS/environment components. Tests that need fixes are not changed:
```
LLVM :: CodeGen/AMDGPU/fabs.f64.ll
LLVM :: CodeGen/AMDGPU/fabs.ll
LLVM :: CodeGen/AMDGPU/floor.ll
LLVM :: CodeGen/AMDGPU/fneg-fabs.f64.ll

LLVM :: CodeGen/AMDGPU/r600-infinite-loop-bug-while-reorganizing-vector.ll
LLVM :: CodeGen/AMDGPU/schedule-if-2.ll
```
Small split change from D146023.
Migrate elf-notes to v4 and fix llvm-readobj to work with PAL metadata.

Summary:
This is part of the leftover work for https://reviews.llvm.org/D143138.
In this work, we pass code object version as an argument to initialize target ID
and use it for targetID dump.

Summary:
This patch introduces a mechanism to check the code object version from the module flag, This avoids checking from command line.
In case the module flag is missing, we use the current default code object version supported in the compiler.
For tools whose inputs are not IR, we may need other approach (directive, for example) to check the code
object version, That will be in a separate patch later.
For LIT tests update, we directly add module flag if there is only a single code object version associated with all checks in one file.
In cause of multiple code object version in one file, we use the "sed" method to "clone" the checks to achieve the goal.

If no pal metadata is given, default to the msgpack format instead of
the legacy metadata. This makes tests better readable.

There is some code that can be shared between GNU/LLVM styles.
Also, this fixes 2 inconsistencies related to dumping unknown note types:
1) For GNU style we printed "Unknown note type: (0x00000003)" in some cases, and
"Unknown note type (0x00000003)" (no colon) in other cases.
GNU readelf always prints `:`. This patch removes the related code
duplication and does the same.
2) For LLVM style in some cases we printed "Unknown note type (0x00000003)",
but sometimes just "Unknown (0x00000003)". The latter is the right form, which
is consistent with other unknowns that are printed in LLVM style.
Rebased on top of D87453.

We use both -long-option and --long-option in tests. Switch to --long-option for consistency.
In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.
While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

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
