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.

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!!!!!!

fix stack mapping code to do as many passes as necessary
...
Previously, we had been doing exactly two passes over the event log to
caculate the stack object reference map at each trace point. It turns
out the correct number of passes depends on how many incorrect
assumptions we make about what the stack looks like at instructions with
multiple predecessors (i.e. targets of jumps and branches).
Each time we detect we've made one or more incorrect assumptions during
a pass, we must do another pass to correct those assumptions. That pass
may in turn reveal further incorrect assumptions, and so on.
