This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.
Note that the code generating backends still manipulate labels as int.
With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

Remove the t_gen_mov_TN_reg and t_gen_mov_reg_TN wrappers: the
latter is completely unused, and the former only used in a few
places (which are thus inconsistent with the rest of the decoder
which directly accesses cpu_R[]).

Split out TCG initialization from cpu_cris_init(). Avoid CPUCRISState
dependency for v10-specific initialization and for non-v10 by inlining
the decision into the initfn as well.

Add an explicit CPUCRISState parameter instead of relying on AREG0, and
use cpu_ld* in translation and interrupt handling. Remove AREG0 swapping
in tlb_fill(). Switch to AREG0 free mode

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.
Use cpu_abort() when in CPU context, abort() otherwise.

CRISv10 cores (unlike v32) do not take any interrupts while delayed
jumps are pending (delay slots).
