cmd/internal/obj/loong64: add support for MOV{GR2FCSR/FCSR2GR/FR2CF/CF2FR} instructions
Go asm syntax example:
MOVV R4, FCSR0
MOVV FCSR1, R5
MOVV F4, FCC0
MOVV FCC1, F5
Equivalent platform assembler syntax:
movgr2fcsr fcsr0, r4
movfcsr2gr r5, fcsr1
movfr2cf fcc0, f4
movcf2fr f5, fcc1
Ref: https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html
This change also merges the case of floating point move instructions
and add checks for the range of special registers.
