generateReificationPreamble

We're at a point where reification has been requested. A StackReifier has already been stashed in the Interpreter, and already-popped calls may have already queued actions in the reifier, to be executed in reverse order.

First, we stash the live registers in a bogus continuation that will resume at the specified target (onReification's target), which must be an L2_ENTER_L2_CHUNK. Then we create an action to invoke that continuation, and push that action onto the current StackReifier's action stack. Finally, we exit with the current reifier. When the L2_ENTER_L2_CHUNK is reached later, it will restore the registers and continue constructing the real continuation, with the knowledge that the Interpreter.getReifiedContinuation represents the caller.
