ART: Compiler support for invoke-polymorphic.
Adds basic support to invoke method handles in compiled code.
Enables method verification for methods containing invoke-polymorphic.
Adds k45cc/k45rc output to Instruction::DumpString() which
was found to be missing when enabling verification.
Include stack traces in test 957-methodhandle-transforms for
failures so they can be easily identified.
Bug: 30550796,33191393
Test: art/test/run-test 953
Test: m test-art-run-test
