60873e298c [AMDGPU] Prevent post-RA scheduler from breaking memory clauses
The pre-RA scheduler does load/store clustering, but post-RA
scheduler undoes it. Add mutation to prevent it.

2e48864110 AMDGPU: Cleanup subtarget features
Try to avoid mutually exclusive features. Don't use
a real default GPU, and use a fake "generic". The goal
is to make it easier to see which set of features are
incompatible between feature strings.

Most of the test changes are due to random scheduling changes
from not having a default fullspeed model.

1baa360f32 CodeGen: Let frame index value type match alloca addr space
Recently alloca address space has been added to data layout. Due to this
change, pointer returned by alloca may have different size as pointer in
address space 0.

However, currently the value type of frame index is assumed to be of the
same size as pointer in address space 0.

This patch fixes that.

Most targets assume alloca returning pointer in address space 0, which
is the default alloca address space. Therefore it is NFC for them.

AMDGCN target with amdgiz environment requires this change since it
assumes alloca returning pointer to addr space 5 and its size is 32,
which is different from the size of pointer in addr space 0 which is 64.
