[AMDGPU] Remove post-PromoteAlloca SROA run

[Pierre-vh]

Summary

PromoteAlloca now uses SSAUpdater, it doesn't need SROA to clean-up after it anymore.

Internal testing shows no noticeable performance impact.

This is a question for my curiosity. Presumably if the 80 bytes/lane for %alloca is now on the stack, shouldn't we expect some other value like VGPRs to go down by 80 bytes (-20 VGPRs)?

Mechanically that's not really how it works. In this case the stack isn't actually used for anything other than filler content (it's kind of a bug this was optimized out to begin with, this memset probably should have been volatile)

@arsenm There is a crash in amdgpu_isel.test from check-llvm-tools-updatetestchecks
This function fails ISel:

; RUN: llc -mtriple=amdgcn-amd-amdhsa -stop-after=finalize-isel -debug-only=isel -o /dev/null %s 2>&1 | FileCheck %s

define i64 @i64_test(i64 %i) nounwind readnone {
  %loc = alloca i64
  %j = load i64, i64 * %loc
  %r = add i64 %i, %j
  ret i64 %r
}

The FrameIndex fails:

t25: i32,ch = load<(dereferenceable load (s32) from %ir.loc, align 8)> # D:1 t0, FrameIndex:i64<0>, undef:i64

LLVM ERROR: Cannot select: t6: i64 = FrameIndex<0>
In function: i64_test

Likewise there is a regression in amdgpu_generated_funcs.ll tests.

I think SROA was doing some (good) stuff for these tests.
A simple fix seems to be to enable optimizations (-O3 works) for the crash.

I would suggest to just use O3 there and open a separate (internal or external) ticket for that ISel failure. What do you think?

[Pierre-vh]

Add test updates

This test is just broken. It's using the wrong address space for the alloca and sroa just happened to delete it. Also this should use opaque pointers

Fixed this in 1f0d24ce24e92ed69f949d6974b87a10af27bd2b
