Sintendo 8964612577 Jit64: boolx - Eliminate read dependency
For certain occurrences of nandx/norx, we declare a ReadWrite constraint
on the destination register, even though the value of the destination
register is irrelevant. This false dependency would force the RegCache
to generate a redundant MOV when the destination register wasn't already
assigned to a host register.

Example 1:
BF 00 00 00 00       mov         edi,0
8B FE                mov         edi,esi
F7 D7                not         edi

Example 2:
8B 7D 80             mov         edi,dword ptr [rbp-80h]
8B FE                mov         edi,esi
F7 D7                not         edi
