jni: Fast path for @FastNative annotated java methods
Adds a faster path for java methods annotated with
dalvik.annotation.optimization.FastNative .
Intended to replace usage of fast JNI (registering with "!(FOO)BAR" descriptors).
Performance Microbenchmark Results (Angler):
* Regular JNI cost in nanoseconds: 115
* Fast JNI cost in nanoseconds: 60
* @FastNative cost in nanoseconds: 36
Summary: Up to 67% faster (vs fast jni) JNI transition cost
