[PATCH] D47532: [ASTImporter] Import the whole redecl chain of functions

[Gabor Marton via Phabricator via cfe-commits]

martong added a comment.

The broken lldb tests are fixed with a minor change. We no longer load the Decls from the
external source during the call of `DeclContext::containsDecl`.  A new function
`DeclContext::containsDeclAndLoad` is added which does a load and calls
`containsDecl`.
