I don't what Intel's original failure looked like, but here's a test that should reproduce this with -run-pass=machinelicm   https://reviews.llvm.org/P8267  needs more cleanup.

I hacked the MIR just before machinelicm by sinking the CMP64mi32 and SETCCr into the loop. That makes MachineLICM want to unfold it since the load part is invariant being from a constant global.
