[cfe-dev] clang and gcc implement __PRETTY_FUNCTION__ differently

After some poking around I realized that I've seen code like this
somewhere. This is exactly what  getTemplateInstantiationPattern does,
it even handles the explicit specialization case that I wasn't aware
of. But I still can't think of the test case where repeated calls to
getInstantiatedFromMemberTemplate are needed, please help.

I think that you're wrong on this one, this loop is used only to
collect classes that have template parameters. This is how I print the
template parameter names inside the square brackets.
getQualifiedNameAsString prints the class names, I haven't touched
that part so nothing gets skipped.
