Revert "Revert "ART: Enable Jit Profiling in Mterp for arm/arm64""
Fixes: missing sign extension in iget template
Call to wrong branch profiling helper in arm/goto_16 and arm/goto_32
Missing export PCs
Reworks: Branch handlers to reduce cost of branch profiling.
Re-enables Jit profiling for both Arm and Arm64.
Performance note:
Branch profiling is relatively expensive, though the real
cost will depend on branch frequency. Taking a very
branch intensive benchmark, CaffeineMark's logic test, we
see the following scores (higher is better):
Mterp (profiling off) 6187
Mterp (profiling on) 4305
Switch (profiling off) 3931
Switch (profiling on) 2032
