fanzha02 6656269288 cmd/asm: add error check for move constant instructions on arm64 
The current Go assembler encodes "MOVK $(0<<16|32|48), Rd" as the
same binary with "MOVK $0, Rd", but for arm64 move constant instructions
MOVK, MOVN and MOVZ, "op $0, Rd" and "op $(0<<16|32|48), Rd" have
different semantics. In order not to change the way the assembler
frontend parses constants, this patch adds a check for the zero shifts.
