cddea7187d preliminary support for using OpenJDK's class library 
Whereas the GNU Classpath port used the strategy of patching Classpath
with core classes from Avian so as to minimize changes to the VM, this
port uses the opposite strategy: abstract and isolate
classpath-specific features in the VM similar to how we abstract away
platform-specific features in system.h.  This allows us to use an
unmodified copy of OpenJDK's class library, including its core classes
and augmented by a few VM-specific classes in the "avian" package.

17c1a552d5 break each Class, Field, and Method into separate classes 
In order to facilitate making the VM compatible with multiple class
libraries, it's useful to separate the VM-specific representation of
these classes from the library implementations.  This commit
introduces VMClass, VMField, and VMMethod for that purpose.

4c0ede8b9a reuse JNI references when possible 
Before allocating a new reference in NewGlobalReference or when
creating a local reference, we look for a previously-allocated
reference pointing to the same object.  This is a linear search, but
usually the number of elements in the reference list is small, whereas
the memory, locking, and allocation overhead of creating duplicate
references can be large.

5ead8fab17 refactor code responsible for moving data in the compiler 
This is partially to address incorrect code generation for 64-bit
floating-point values on x86_32 and partially to reduce unnecessary
moves.

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.

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.
