[PATCH] D98144: [CodeGenPrepare] Fix isIVIncrement (PR49466)

[Jordan Rupprecht via Phabricator via llvm-commits]

Reverted in 8d20f2c2c66eb486ff23cc3d55a53bd840b36971 <https://reviews.llvm.org/rG8d20f2c2c66eb486ff23cc3d55a53bd840b36971>. Although this fixes a crash, it also introduces a compile timeout (haven't checked if it's a true infinite loop or just _really_ slow) on other code. The reproducer is in the commit message.
