[PATCH] D29220: [InstCombine] Re-enable guard canonicalization for AND and NOT OR

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev created this revision.

The following changes:

r293061: "[InstCombine] Canonicalize guards for NOT OR condition"
r293058: "[InstCombine] Canonicalize guards for AND condition"

were reverted by the change

https://reviews.llvm.org/rL293227: "Revert a couple of InstCombine/Guard checkins"

because they contained a bug related to handling guards with multiple
arguments. The problem was that the extra arguments of the initial
guard were not passed to the newly-created guards.

This patch re-enables canonicalization of guards for AND and NOT OR
conditions and adds proper tests for them.
