  "Recommit "[AggressiveInstCombine] Lower Table Based CTTZ""

This reverts commit 053841c5624ca7eacd108a26071d8a1cefe1bebd.

We faced a use-after-free after pushing the D113291, since the
foldSqrt() has a call to eraseFromParent(). The function
should be at the end of the main loop that folds the patterns.
This patch fixes that.
