Ryan Houdek 2bcc46c9e5 Implements FFREEP support in the OpDispatcher
There's some history for this instruction. It is not in the official
instruction documentations from AMD or Intel but it is supported on
almost every x87 supporting CPU (I think there was some Cyrix that
missed it?)

This was originally implemented by accident on the Intel 80287 CPU.
It was then periodically documented in random documentation.

The instruction behaves exactly like FFREE but then pops the stack after
the operation.
For our current implementation of FFREE, which is a NOP, we just need to
pop the stack.
