[PATCH] D34726: AMDGPU/SI: Do not insert an instruction into worklist twice in movetovalu

[Alfred Huang via Phabricator via llvm-commits]

alfred.j.huang added a comment.

Switch to SmallSetVector in place of SmallPtrVector so an item is inserted into the container once only.  The order of pushing and popping are the same as before.
