This revision now requires changes to proceed.

I think we should override getGCCAddlRegNames to map vs* to reg numbers , 
this can avoid unnecessary renaming from `vs32` to `v0` in clobber list.

`  call void asm sideeffect "lxvw4x %vs32, 0, $2\0A\09stxvw4x %vs32, 0, $1", "=*m,r,r,~{vs32}"(i32* %0, i32* %1, i32* %d) #1, !srcloc !3`
