Revert "Update amdgpu_gfx functions to use s0-s3 for inreg SGPR arguments on targets using scratch instructions for stack #78226" (#86273)
Reverts llvm/llvm-project#81394
This reverts commit 3ac243bc0d7922d083af2cf025247b5698556062.
It is not handling RSrc registers s0-s3 correctly. This leads to a
broken test, where it expects s0-s3 as function argument and uses it as
RSrc register as well.
We need to re-visit the patch, but apparently we only want to have s0-s3
as
argument registers if we don't need them as RSrc registers.

[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:

AMDGPU: Scratch instructions are trivially disjoint from SMEM and buffer instructions (#65287)
Scratch instructions are always in addrspace(5), which can only alias
with flat (and itself). SMEM and buffer instructions can never reference
those address spaces, so they are trivially disjoint.
