Due to mapping changes, we now rarely place the code_gen_buffer

So, always use indirect calls for tail calls, which allows us to
avoid clobbering %o7, and therefore we need not save and restore it.

As an aside: I found it a bit confusing that tcg_out_mov()
takes a 'type' argument but ignores it, whereas tcg_out_mov_delay()
doesn't take a 'type' argument at all.
Mm. tcg_out_mov() is common to all tcg backends, and some hosts do use the type argument.
I didn't add one to tcg_out_mov_delay() because sparc didn't need one.
