[PATCH] D89170: [AMDGPU] Select flat scratch instructions where available

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec planned changes to this revision.
rampitec added a comment.

Testing showed couple problems:

1. Debug tablegen asserts with this.
2. Using null register in flat scratch does not work, but it needs a new ST addressing mode of GFX10. I will create a separate patch to support ST mode.
