eric fang 9726c78539 cmd/asm: add check for register and shift/extension combination on arm64 
The current code lacks a check on whether the register and shift/extension
combination is valid, for example the follow instructions also compiles.
	ADD     F1<<1, R1, R3
	ADD     V1<<1, R1, R3
	MOVW    (R9)(F8.SXTW<<2), R19
	VST1    R4.D[1], (R0)

Actually only general registers can perform shift operations, and element
and arrangement extensions are only applicable to vector registers. This
CL adds a check for the register and shift/extension combination on arm64.
