[PATCH v2 00/12] target/microblaze improvements

From: Richard Henderson

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.

In addition, cpu vmstate is filled in and interrupt logging is tidied.
