ART: Reject branch/switch/throw to move-result.

move-result* instructions must occur after invoke instructions,
however it was still possible to branch or switch to a move-result*
instruction with creative DEX manipulation. The verifier now rejects
this situation, as well as having a move-result* instruction as the
first instruction in a try block's handler. This now ensures that
move-result* must happen dynamically after an invoke, not just
statically.
