Methods can now be qualified with address spaces to prevent
undesirable conversions to generic or to provide custom
implementation to be used if the object is located in certain
memory segments.
This commit extends parsing and standard C++ overloading to
work for an address space of a method (i.e. implicit 'this'
parameter).
