[PATCH] D16579: Warn if friend function depends on template parameters.

[Serge Pavlov via cfe-commits]

Changed implementation of friend function set.

Friend functions declared in template classes are not added to redeclaration chains,
but access to them is needed to make some checks. This change allows using the
set of friend functions not only to emit particular warning but also to serve as a
registry of file-level friend functions.
