[PATCH] D104075: [ScalarEvolution] Merge howManyGreaterThans with howManyLessThans.

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Note to self: differences between old and new gt codepath that need tests:

1. Now compute max trip count even if RHS is not invariant.
2. Now more aggressive with strides that are not known positive (although this codepath currently has issues...)
3. Now use isUBOnWrap() for stride greater than one.
4. Now compute MaxOrZero.
