c8cc7d931b maintain a table to look up methods called via JNI 
This simplifies the JNI implementation for looking up methods.  It also
fixes a bug where an applications calls GetStaticMethodID with class A
and then calls CallStatic<Type>Method with class B which extends A.  The
old code would look in the wrong method table and thus call the wrong
method.

Joel Dice
0b79ab4fed fix race condition in compile function 
1. Thread A calls function F, which needs to be compiled.  So it
compiles it.
 2. Thread B calls function F, sees that it's already been compiled and
so runs it.
 3. Thread B calls function G from function F, and G needs to be
compiled, but it needs to acquire the class lock first, which A owns.
 4. Thread A causes a GC, walks thread B's stack, but function F has not
yet been added to the method tree, so it thinks the stack has no frames.
 5. Thread A finally adds function F to the method tree.
 6. Thread A causes another GC and walks thread B's stack again, and
this time it finds function F in the method tree.
 7. AAAARRRRRGGGHHH!!!!!!
