tcg/tci: Implement goto_ptr
This operation is critical to staying within the interpretation
loop longer, which avoids the overhead of setup and teardown for
many TBs.
The check in tcg_prologue_init is disabled because TCI does
want to use NULL to indicate exit, as opposed to branching to
a real epilogue.
