Reproducer

LICM doesn't handle intrinsics. Compiler should recognize most of intrinsics
and hoist them out of the loop if their arguments are loop invariants.

This seems to be the general problem, but I may be mistaken (and actually I
hope so!). The intrinsics that I've stuck with is @llvm.x86.sse41.blendvps().

I've attached short reproducer.
