cmd/internal/obj/loong64: add FLDX,FSTX,LDX.STX instructions support
The LDX.{B,BU,H,HU,W,WU,D},STX.{B,H,W,D}, FLDX.{S,D}, FSTX.{S,D} instruction
on Loong64 implements memory access operations using register offset
Go asm syntax:
MOV{B,BU,H,HU,W,WU,V} (RJ)(RK), RD
MOV{B,H,W,V} RD, (RJ)(RK)
MOV{F,D} (RJ)(RK), FD
MOV{F,D} FD, (RJ)(RK)
Equivalent platform assembler syntax:
ldx.{b,bu,h,hu,w,wu,d} rd, rj, rk
stx.{b,h,w,d} rd, rj, rk
fldx.{s,d} fd, rj, rk
fstx.{s,d} fd, rj, rk
