Add a new opcode for 32->64 bit sign-extended immediate, with warning on the number not matching. This unfortunately calls for an audit of all the \4[0123] opcodes, if they should be replaced by \25[4567]. This only replaces one instruction (MOV reg64,imm32); other instructions need to be considered. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
