* Code: Generic 64-bit unary operation. Provide an "instr" variable and a
* preinstr variable that together specify an instruction that

*
* For: neg-double, neg-long, not-long
*
* Description: Perform the identified unary operation on the source
* register, storing the result in the destination register
*
* Format: B|A|op (12x)
*
* Syntax: op vA, vB
