To clarify, if MXU is present (a cpu defined to have MXU instructions is
selected) we will never run any of the other special2 commands? That would
actually simplify the implementation.
Also I understand the want for clean code, I appreciate the comments.

I will re-work each of the mxu_gen_ functions to check for MXUEN and jump
over the implementation of the instruction if not enabled.
I would like to clarify the structure of the switch statement before
implementing it.
I was originally planning on checking if there was a MXU hit and MXUEN was s

One more thing to check is MXUEN bit of MXU control register. This should be
done before handling any MXU instructions, except S32M2I/S32I2M.

I see that I can check the loongson instructions by checking for
INSN_LOONGSON2F. Using MXU if that is not set
What should I check for the mult or misc instructions that were there first?
