[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:

```
  LLVM :: CodeGen/AMDGPU/fabs.f64.ll
  LLVM :: CodeGen/AMDGPU/fabs.ll
  LLVM :: CodeGen/AMDGPU/floor.ll

da0293e3cc AMDGPU: Bulk update some r600 tests to opaque pointers 
r600.amdgpu-alias-analysis.ll has something strange going on where
AliasAnalyisEvaluator's printing is reproducing the typed pointer
syntax.

657ef48a88 AMDGPU: Select VOP3 form of sub 
The VOP3 form should always be the preferred selection form to be
shrunk later.

The r600 sub test needs to be split out because it asserts on the
arguments in the new test during the calling convention lowering.
