  MIPS: Fix llvm.{min,max}num for R6 (#93125)

MIPS max.fmt/min.fmt instructions is IEEE2008 compatiable. If either
argument is sNaN, the result will be NaN.

So we define fminnum_ieee instead of fminnum in Mips32r6InstrInfo.td. We
also should define fcanonicalize. So that we can define fminnum as
expand to fcanonicalize and fminnum_ieee.
