[PATCH] D11051: Extend LICM to hoist loop invariant GEP out

[Andrew Trick]

atrick added a comment.

If you need to do this transformation is cases where the inbounds flag will be dropped it seems best to do it late in the pipeline (maybe even after LSR) as a target-controlled optimization. Arranging for the hoisting to happen seems like the easy part of this problem.

Out of curiosity, I wonder if the LSR fix here http://reviews.llvm.org/D11212 has any impact on this test case.
