Joel Dice 453ceb42ab implement lazy class/field/method resolution in JIT compiler
Unlike the interpreter, the JIT compiler tries to resolve all the
symbols referenced by a method when compiling that method.  However,
this can backfire if a symbol cannot be resolved: we end up throwing
an e.g. NoClassDefFoundError for code which may never be executed.
This is particularly troublesome for code which supports multiple
APIs, choosing one at runtime.

The solution is to defer to stub code for symbols which can't be
resolved at JIT compile time.  Such a stub will try again at runtime
to resolve the needed symbol and throw an appropriate error if it
still can't be found.
