[PATCH] D61922: [IndVarSimplify] Rotate exit comparisons to make them more invariant

[Philip Reames via Phabricator via llvm-commits]

No longer actively pursuing.  The idea is reasonable, and only partly overlaps with LFTR, but all of the non-reduced motivating cases are covered by multiple exit LFTR.

If anyone wants to pick this up, feel free.  There's probably some commonality with the existing simplifyIVUsers code, particularly the truncate path.  Might be worth reframing in those terms.  Or maybe I'll get back to this someday.
