Changes v2-v3:
* Make more use, where appropriate, of normal pointer arithmetic under
the new type. In particular, if the target previously computed
(label - code_ptr) >> 2
using byte arithmetic, we can now arrange for this to be just
label - code_ptr
with the shift added by the compiler. Given that technically a right
shift of a negative value is implementation defined (may the death of
catering to one's compliment machine come soon), having the compiler do
this is going to eliminate one more stupid warning from some sanitizer.
* Finish conversion of all tcg backends.
