[PATCH] D123127: [AST] Add a new TemplateName for templates found via a using declaration.

[Haojian Wu via Phabricator via cfe-commits]

hokein updated this revision to Diff 422310.
hokein added a comment.

reland version: there is no freebit in the TemplateName's PointerUnion to store
5 different pointer types in 32-bit build, instead we change the TemplateDecl to
NamedDecl, which can be used to hold the TemplateDecl and UsingShadowDecl.
