Revert "Revert "Revert "Revert "Basic obsolete methods support""""

A GetDeclaringClass()->GetDexCache() got inserted during the
merge/review process meaning that we would try to access incorrect
dex-cache in obsolete methods in some situations.

Also when using tracing we would loop forever (or at least until an
OOM error) in test 916 due to tracing forcing InterpretOnly mode
meaning methods would never be jitted.

Bug: 32369913
Bug: 33630159

Test: ART_TEST_TRACE=true \
      ART_TEST_JIT=true   \
      ART_TEST_INTERPRETER=true mma -j40 test-art-host

This reverts commit f6abcda293b115a9d7d8a26376ea2dcf2d1dc510.
