[AMDGPU,test] Change llc -march= to -mtriple= (#75982)
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:

0f94d2b385 [AMDGPU] GFX11: automatically release VGPRs at the end of the shader
GFX11 has a new message type MSG_DEALLOC_VGPRS which can be used to
release a shader's VGPRs. Sending this at the end of a shader (just
before the s_endpgm) can help overall system performance in cases where
the s_endpgm would have to wait for outstanding VMEM stores to complete
before releasing the VGPRs.

c155a944fb [AMDGPU] GFX11 CodeGen support for MIMG instructions
This includes:
- New llvm.amdgcn.image.msaa.load.* intrinsics
- NSA changes, because MIMG-NSA is now limited to 3 dwords
- Split CD forms of IMAGE_SAMPLE instructions out into separate
  test files since they are no longer supported in GFX11

d28624a209 [AMDGPU] Stop adding an implicit def of vcc_hi for wave32
This doesn't seem to be needed for anything.

8756869170 [AMDGPU] Add a16 feature to gfx10
Based on D72931

This adds a new feature called A16 which is enabled for gfx10.
gfx9 keeps the R128A16 feature so it can share all the instruction encodings
with gfx7/8.

63718b214a [AMDGPU] support image load/store a16
Our a16 support was only enabled for sample/gather and buffer
load/store, but not for image load/store operations (which take an i16
as the pixel index rather than a half).

Fix our isel lowering and add test cases to prove it out.
