Temporarily Revert "Add basic loop fusion pass."

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

[InstCombine] add folds for xor-of-icmp signbit tests (PR36682)
...
This is a retry of r328119 which was reverted at r328145 because
it could crash by trying to combine icmps with different operand
types. This version has a check for that and additional tests.
Original commit message:
This is part of solving:
