This is a follow-on to 6334a968eec3 ("tcg/optimize: Canonicalize
subi to addi during optimization"), which I wrote at the end of
the previous devel cycle, then forgot about during the current.

In addition to sub->add, canonicalize andc->and etc.

The early expansion that we produce for deposit does not fold
constants well; expand unsupported deposit during optimize.
