fix openjdk-src bootimage build
...
The main change here is to use a lazily-populated vector to associate
runtime data with classes instead of referencing them directly from
the class which requires updating immutable references in the heap
image. The other changes employ other strategies to avoid trying to
update immutable references.

more work towards OpenJDK classpath support
...
The biggest change in this commit is to split the system classloader
into two: one for boot classes (e.g. java.lang.*) and another for
application classes. This is necessary to make OpenJDK's security
checks happy.
The rest of the changes include bugfixes and additional JVM method
implementations in classpath-openjdk.cpp.

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.

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.

fix process=interpret class initialization regression
...
A long time ago, I refactored the class initialization code in the VM,
but did not notice until today that it had caused the
process=interpret build to break on certain recursive initializations.
In particular, we were not always detecting when a thread recursively
tried to initialize a class it was already in the process of
initializing, leading to the mistaken assumption that another thread
was initializing it and that we should wait until it was done, in
which case we would wait forever.
This commit ensures that we always detect recursive initialization and
short-circuit it.

We now support immortal objects, which the GC will scan for references
but not consider for collection. On x86_64, we allocate JIT code memory
via mmap, which lets us map memory into the bottom 2GB of the address
space, ensuring that 32-bit relative jumps and calls work.
