Constructor / Destructor Prologue / Epilogue for Stack Exception Handling

[P-p-H-d]

Constructor (and destructor) need to use user-defined prologue / epilogue.
This is in order to register the constructed object into a proper Stack Exception Handling so that exceptions throwing may work reliably.

Proposal:
M_CONSTRUCTOR_PROLOGUE(object, oplist);
M_CONSTRUCTOR_EPILOGUE(object, oplist);
M_DESTRUCTOR_PROLOGUE(object, oplist);
M_DESTRUCTOR_EPILOGUE(object, oplist);

Object creation will need to add all sub-objects into the stack, then unstack all to push instead the root object (which will recursively remove them).
