[PATCH] D31539: Hoisting invariant.group in LICM

[Piotr Padlewski via Phabricator via llvm-commits]

Prazek created this revision.

The !invariant.group loads having pointer operand that dominates
the loop body can be hoisted, because we know the load will produce
the same value in every loop step.
