6e6035505c 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.

3e6c30a4b5 always return an 8-byte value (or void) from native functions called from Java 
This is important on the 32-bit OS X PowerPC ABI, since the location
of the low 32-bits of a return value change depending on whether the
entire value is 64-bits or not.

6f1d02dae7 remove the libstdc++ dependency once and for all 
The trick is to make all destructors non-virtual.  This is safe because
we never use the delete operator, which is the only case where virtual
destructors are relevant.  This is a better solution than implementing
our own delete operator, because we want libraries loaded at runtime to
use the libstdc++ version, not ours.

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.

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!!!!!!
