Revert "Revert "Revert "Revert "ART: Enable Jit Profiling in Mterp for arm/arm64""""

This reverts commit 5d03317a.

We need to catch all possible cases in which new instrumentation appears
or the debugger is attached, and then switch to the reference interpreter
if necessary.  We may, in a future CL, use the alt-mterp mechanism to accompish
this (as did Dalvik).

Only enables Arm64 for now.  Once it survives extended testing, will enable
arm and update x86.

Updated OSR handling to match other interpreters.
