RecursiveASTVisitor:

We don't create any declaration to mark the explicit instantiation of function
templates other than the instantiation itself, so visit that when traversing
the function template decl.

This is a temporary fix, pending the creation of a Decl node to represent the
explicit instantiation.

Patch by Daniel Jasper!
