Fix the showstopping coherency bug.
...
This bug is the result of an optimization gone wrong. To keep
performance high, we cache the last-used MIPS instruction and data
segments (useg, sseg, kseg, uxseg, etc.), instead of recomputing the
segment 1-2x per cycle (it's expensive).
Unfortunately, this means that the segments need to be manually
invalidated at certain points, lest one risks using a segment which
may no longer be valid. This was the case for this bug, in which the
segments were not invalidated following an ERET (exception return).

Pass IW to each opcode function.
...
Instead of having almost every opcode function load IW off the
stack through the VR4300 pointer, just pass it as an argument on
the stack to reduce binary size and hoist a load up.
Thanks go out to Narann for this idea.
