The introduction of tcg_gen_deposit_z_* pre-dates the introduction
of tcg_constant_*.  These days, a reasonably up-to-date translator
should not need to manually choose between the two deposit functions,
but instead rely on any zero register to supply tcg_constant*(0)
as a source operand.

In addition, the hppa front end has some special cases for insertion
of a constant (depiw instruction), as opposed to the current insertion
into a constant.
