[PATCH] D16478: Always build a new TypeSourceInfo for function templates with parameters

[Yaron Keren via cfe-commits]

The instantiated does get a new collection of ParmVarDecls while getting
the pattern Type which points to the pattern ParmVarDecls. So the
ParmVarDecls pointed in the instantiated are not the same as those pointed
by its Type.

Traversing by Type or by the Decl finds a different set of ParmVarDecls
which seems an inconsistency or at least a surprise.
