Subject: [PATCH 1/2] [InstallAPI] Collect frontend attributes during &
ObjCInterface Records.
* This patch introduces a inherited container class for holding
records and attributes only collectable from the clang frontend.
* This also prunes out collecting declarations from headers that aren't
considered input to installapi.
* Use these constructs for collecting global objective-c interfaces.
