Is the root problem that we don't have FMF on any FP select? We discussed that in:
https://bugs.llvm.org/show_bug.cgi?id=38086

If that's correct, I think we should make that change instead of making matchSelectPattern more complicated.

We're going to have to fix this anyway to solve cases that aren't min/max like:
