Revert "Revert "ART: Compiler support for invoke-polymorphic.""

This reverts commit 0fb5af1c8287b1ec85c55c306a1c43820c38a337.

This takes us back to the original change and attempts to fix the
issues encountered:

- Adds transition record push/pop around artInvokePolymorphic.
- Changes X86/X64 relocations for MacSDK.
- Implements MIPS entrypoint for art_quick_invoke_polymorphic.
- Corrects size of returned reference in art_quick_invoke_polymorphic
  on ARM.
