* Dont flush the entire qemu tlb when the $pid changes. Instead we go through
  the guests TLB and choose entries that need to be flushed.
* Add env->dslot and handle delayslots at pageboundaries.
* Remove some unused code.

instruction without running the hardware interrupts.

* Support both the I and D MMUs and improve the accuracy of the MMU model.
* Handle the automatic user/kernel stack pointer switching when leaving or entering user mode.
* Move the CCS evaluation into helper funcs.
* Make sure user-mode cannot change flags only writeable in kernel mode.
* More conversion of the translator into TCG.
* Handle exceptions while in a delayslot.
