[RFA] Add parsing support for C++ operators

[Keith Seitz <keiths at redhat dot com>]

Hi,

The attached patch adds support to the parser for C++ operators. This 
has the additional benefit of negating the need to single-quote operator 
names during parsing, e.g., "print &foo::operator delete[] (void*)" now 
works.

Comments/questions/concerns?
