Add suspend checks to special methods.

Generate suspend checks at the beginning of special methods.
If we need to call to runtime, go to the slow path where we
create a simplified but valid frame, spill all arguments,
call art_quick_test_suspend, restore necessary arguments and
return back to the fast path. This keeps the fast path
overhead to a minimum.
