Improve performance of JNI field operations.

Change improves performance of JniField Fadden test by around 25%, we're still
2x slower than Dalvik.
Aggressively inline ScopedObjectAccess, Thread::SetState and field helpers.
If we're not contention logging don't call MilliTime (avoids a double register
spill).
Remove (broken?) thread checks in scoped object access, they are redundant with
ones being performed in check JNI.
