cmd/internal/obj/loong64: add support for instructions FTINT{RM/RP/RZ/RNE}.{W/L}.{S/D}
These instructions convert floating-point numbers to fixed-point numbers
with the specified rounding pattern.
Go asm syntax:
FTINT{RM/RP/RZ/RNE}{W/V}{F/D} FJ, FD
Equivalent platform assembler syntax:
ftint{rm/rp/rz/rne}.{w/l}.{s/d} fd, fj
