Support Bitwise OR for qualified_type_def::CV better

Browse Source 
* src/abg-ir.h (qualified_type_def::CV_RESTRICT): New enumerator
	for the qualified_type_def::CV enum.
	(operator|(qualified_type_def::CV, qualified_type_def::CV)): New
	declaration.
	* src/abg-ir.cc (operator|(qualified_type_def::CV,
	qualified_type_def::CV)): New definition.
	* src/abg-reader.cc (build_qualified_type_decl): No need for
	casting the result of bitwise or between instances of
	qualified_type_def::CV.
