Adding the ability to enable memory overlap check in assignment to avoid unneeded temporary memory allocation

1

Currently the default behaviour of `xsemantic_base::operator=(const xexpression& e)` is to create a temporary copy of `e` to avoid any problems with overlapping memory. However, if the user doesn't use some...
