zero heap space ahead of time when allocating raw storage and garbage collecting, not when allocating individual objects
...
This helps us support the Java Memory Model without adding a memory
barrier to every object allocation. It's also potentially more
efficient, since we zero out each heap segment all at once instead of
bit-by-bit with each object allocation.

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!!!!!!
