[PATCH v3 00/19] target/microblaze improvements

[Richard Henderson]

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.
