Add plugin for testing method tracing speed.
It can be useful to test how much overhead the ART method tracing
infrastructure has. Since normal method tracing APIs (eg
-Xmethod-trace, JVMTI events) have significant overhead for
synchronization or other reasons we created a simple plugin that
begins method tracing but doesn't record or even look at the trace
events. This lets us have a rough idea how much simply sending these
events costs us.
Test: ./test/run-test --host \
--runtime-option \
-Xplugin:$ANDROID_HOST_OUT/lib/libtracefast-trampolined.so \
