Richard Henderson e01d60f211 tcg/sparc: Add tcg_out_jmpl_const for better tail calls
Due to mapping changes, we now rarely place the code_gen_buffer
near the main executable.  Which means that direct calls will
now rarely be in range.

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