[PATCH] D125968: [AMDGPU] Mark s_getreg as having side effects instead of reading memory

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

The motivation here is to cut down on MachineInstrs that are marked as mayLoad or mayStore but do not have memoperands, since passes like SIMemoryLegalizer have to treat them very conservatively.
