Johannes Doerfert 8f1e06e258 [ValueTracking] Allow context-sensitive nullness check for non-pointers
Summary:
Same as D60846 and D69571 but with a fix for the problem encountered
after them. Both times it was a missing context adjustment in the
handling of PHI nodes.

The reproducers created from the bugs that caused the old commits to be
reverted are included.
