Do native method bind in jvmti-stress

Extend the jvmti-stress test suite to intercept the NativeMethodBind
event for every method.

Also fix small issue where we tried to add a local reference to a null
thread in ti_method.cc if we had an event trigger before VMInit.

Test: ./test/testrunner/testrunner.py --host --jvmti-stress -j40
