[PATCH] D71467: [FPEnv] Generate constrained FP comparisons from clang

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

The bug with `__builtin_isless` should be a really easy fix; the builtin just needs to be flagged as having custom type-checking, and then we need to make sure we do appropriate promotions on the arguments (but we probably do).
