Jay Foad	ddd3807e69	[AMDGPU] Use new target MMO flag MONoClobber This allows us to set the noclobber flag on (the MMO of) a load instruction instead of on the pointer. This fixes a bug where noclobber was being applied to all loads from the same pointer, even if some of them were clobbered.

[AMDGPU] Use new target MMO flag MONoClobber

This allows us to set the noclobber flag on (the MMO of) a load
instruction instead of on the pointer. This fixes a bug where noclobber
was being applied to all loads from the same pointer, even if some of
them were clobbered.
