44a7c2ecd4 target/sparc: Use tcg_gen_lookup_and_goto_ptr for v9 WRASI 
We incorporate %asi into tb->flags so that we may generate
inline code for the many ASIs for which it is easy to do so.
Setting %asi is common for e.g. memcpy and memset performing
block copy and clear, so it is worth noticing this case.

We must end the TB but do not need to return to the main loop.
