* Factored repeating REX operations into a separate function.
* Fixed instruction matching bug which was preventing compilation of 3-operand SIMD instructions with RIP-relative operand + test.
* Do not adjust offset of RIP-relative reference if it is a literal number, this was causing 0x123(%rip) to assemble as 0x122(%rip) in 3-operand instructions. Now tasm2.pp is the same with and without -Aas. Also fixed the expected result, improved verbosity of diagnostic and removed %norun, so it is actually executed.
+ Disallow high-byte registers in instructions requiring REX + test.
