Re-fix operand access of three mov instructions
Synch with upstream
The python script for generating constants in the bindings does not know how to handle the #if 0 statements included in these files.
Pulling from upstream
Registry access for the destination operand of the conditional move (cmov) opcodes were incorrectly listed as READ | WRITE. Although you would expect the two operands to be compared in this opcode, it instead relies on the associated flag in EFLAGS regardless of the value in the destination operand.

The destination operand of the conditional move (cmov...) instructions incorrectly states that they are READ | WRITE. These instructions actually do not read the destination operand at all, but instead rely on the associated flag set in EFLAGS.
