Move interpreter to ObjPtr
Moved most of interpreter, interpreter_common, interpreter_switch_impl, and some of mterp to ObjPtr. Bug: 31113334 Test: test-art-host ART_TEST_INTERPRETER=true Test: art/tools/run-libcore-tests.sh '--mode=host' '--variant=X32' --debug Change-Id: I0935d18287e1332205c17c5a018aa167788ab897
