Threw away original implementation and took it from https://reviews.llvm.org/D139109. Thanks to @kachkov98 for his work on this, who is listed as a co-author in the commit.

The implementation is mostly copied with small changes and incorporates feedback from reviewers. Took out NFC's for unswitching guards.

Added a bunch of tests.
