  [LegalizeTypes] Support softening FMINIMUM/FMAXIMUM (#115463)

Without this, you get an error "Do not know how to soften the result of
this operator!" when compiling for a soft float target.

The libcall names match those defined in glibc
<https://www.gnu.org/software/libc/manual/html_node/Misc-FP-Arithmetic.html>
and more recently added to LLVM's libc
<https://github.com/llvm/llvm-project/pull/86016>.
