  Intrinsic: introduce minimumnum and maximumnum (#93841)

Currently, on different platform, the behaivor of llvm.minnum is
different if one operand is sNaN:

When we compare sNaN vs NUM:

ARM/AArch64/PowerPC: follow the IEEE754-2008's minNUM: return qNaN.
RISC-V/Hexagon follow the IEEE754-2019's minimumNumber: return NUM. X86:
Returns NUM but not same with IEEE754-2019's minimumNumber as
     +0.0 is not always greater than -0.0.
MIPS/LoongArch/Generic: return NUM.
LIBCALL: returns qNaN.

So, let's introduce llvm.minmumnum/llvm.maximumnum, which always follow
IEEE754-2019's minimumNumber/maximumNumber.

Half-fix: #93033
