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.
