Query only the latest version of an identifier in the PCH chain. Make sure this version holds the entire declaration chain. This is a much saner solution than trying to merge the info from all elements, and makes redeclarations work properly. Expand the declarations test case to cover more compliated cases.

Remove mutable data on TagType and InjectedClassNameType, by instead walking the declaration chain in search of a definition. This is necessary for a sane chained PCH implementation. No observable performance change on Carbon.h syntax-only, and bootstraps cleanly.

 - We don't want to use the Action's own CompilerInstance, because that is only
   initialized during file processing and I like that invariant.

Also, if ParseArgs returns false then abandon execution.

Also, remove unused PluginASTAction::PrintHelp virtual method.
