target/microblaze: Store "current" iflags in insn_start
This data is available during exception unwinding, thus
we can restore it from there directly, rather than saving
it during the TB. Thus we may remove the t_sync_flags()
calls in the load/store operations.
Note that these calls were missing from the other places
where runtime exceptions may be raised, such as idiv and
the floating point operations.
