This ensures the lifetime of reference values on the simulated operand
stack of the interpreter is coupled to a lifetime of the {ThreadImpl}.
We no longer directly store reference values on the stack, but maintain
a separate "reference stack" on the GC'ed heap. This will ensure the GC
traces such references properly.
The new {StackValue} safety wrapper makes sure all use-sites that access
the operand stack properly convert to/from handles when dealing with
reference values.
