[MIPS] match llvm.{min,max}num with {min,max}.fmt for R6 (#89021)
- The behavior is similar to UCOMISD on x86, which is also used to compare two fp values, specifically on handling of NaNs. - Update related tests regarding this change. - The further goal is to implement `llvm.minimum` and `llvm.maximum` intrinsics for MIPS R6 and Pre-R6.
