LoongArch: Set FMAXNUM and FMINNUM as Legal (#139010)

Browse Source 
Now we define FMAXNUM and FMINNUM as IEEE754-2008 with +0.0>-0.0.
LoongArch's fmax/fmin just follow this rules full.

FMAXNUM_IEEE and FMINNUM_IEEE will be removed in future once:

Fixes FMAXNUM/FMINNUM for all targets
The use of FMAXNUM_IEEE/FMINNUM_IEEE are not used by middle end anymore.
