[PATCH] D105209: [WIP][SCEVExpander] Discount cost of umin(x,1) expressions

[Philip Reames via Phabricator via llvm-commits]

reames planned changes to this revision.
reames added a comment.

For future self:

- and reduction trick does not hold when A and B are both non-zero, but with different bits set.
- the original umin(a,1) trick still holds, it's the extension to multiple operands which was wrong
