Version 3:
* Splits out MicroBlazeCPUConfig, and moves some values
out of CPUMBState (env) that are constant configuration
parameters, or derived from configuration parameters.
* Do not save configuration parameters with vmstate.
* Pass around MicroBlazeCPUConfig in the translator.
* Do not set TARGET_ABI32 in configure.
Version 2:
* Includes fixes for iflags that could cause lockups.
It seems it was easier to do so with icount=7, which is what we
do during the replay acceptance tests. This causes TBs to contain
no more than 7 insns, and often less to make up for an incomplete
count elsewhere. Which stressed the iflags bits around delay slots
and imm in ways that pure single-step doesn't.
* cpu vmstate is filled in
* interrupt logging is tidied.
