Sanjay Patel 9397bdc67e [InstCombine] fold fcmp with lossy casted constant ...

This is noted as a missing clang warning in #54222
(and we should still make that enhancement).

Alive2 proofs:

I don't see a single conversion for all predicates
using "getFCmpCode" logic, so other predicates are
left as a TODO item.
