ARM: VIXL32: Pass initial ART tests with new code generator.

- Implement enough codegen to pass ~70 art/tests.

- When ART_USE_VIXL_ARM_BACKEND is defined:
  - Blacklist known-to-fail target tests
  - interpret-only everything except the tests themselves
  - Set a flag to use the VIXL based ARM backend

Test: export ART_USE_VIXL_ARM_BACKEND=true && mma test-art-target && mma test-art-host
