No SuspendChecks when branching to return block
The return basic block is usually placed at the beginning of the DEX
file, making the branches to it back edges where the Optimizing's
graph builder places SuspendCheck instructions, only to be removed
later by the instruction_simplifier pass. Since huge auto-generated
methods tend to contain hundreds/thousands of these, this patch
recognizes the pattern and prevents builder from generating the
redundant check in the first place.
