jni: Do not create a managed frame for @CriticalNative.

Omit managed frame for @CriticalNative methods, do not check
for exceptions and and make a tail call when possible.
Pass the method pointer in a hidden argument to prepare for
implementing late binding for @CriticalNative methods.

This changes only the JNI compiler, Generic JNI shall be
updated in a separate change.

Performance improvements reported by Golem (art-opt-cc):
                                 x86 x86-64    arm  arm64
