C++: Print numeric template arguments in NamePrettyPrinter

Browse Source 
Improve type printed for template specializations with numeric
or bool values.

Code example:
template<bool B, class T> struct enable_if{};
template<class T> struct enable_if<true, T>{ typedef T type; };

In outline: "enable_if<_Tp1, T> <T>" becomes "enable_if<true, T> <T>"

TemplateArgument class holds pointer to numeric literal owned
by CppDocument, so remove Control::squeeze() to not release
numericLiterals in CppDocument::releaseSourceAndAST()

This based on TemplateArgument class introduced in commit
9ee693ee22
