target-arm: Handle always condition codes within arm_test_cc
...
Handling this with TCG_COND_ALWAYS will allow these unlikely
cases to be handled without special cases in the rest of the
translator. The TCG optimizer ought to be able to reduce
these ALWAYS conditions completely.

target-arm: Introduce DisasCompare
...
Split arm_gen_test_cc into 3 functions, so that it can be reused
for non-branch TCG comparisons.

tcg: Change translator-side labels to a pointer
...
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.

tcg: Put opcodes in a linked list
...
The previous setup required ops and args to be completely sequential,
and was error prone when it came to both iteration and optimization.
