[PATCH] D54956: [ValueTracking] Look through casts when determining non-nullness

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

Removed s/zext, moved ptr2int to make sense. Bitcast was my actual use case, int2ptr was not (always) covered before, the ptr2int test case was but only late in computeKnownBits.
