Before ThunkGenerators::slowPathFor() jumps to the target function, it returns the stack to the function entry state. Currently it does this using a pop(callFrameRegister). Instead it should emit a function epilogue(). This will work for architectures that have a link register that the callee will want to save in its prologue in addition to the callFrameRegister.
