When we need the complete set of visible declarations from a declaration context, check whether the primary context---not the current context---has any external visible declarations. Fixes PR13616. llvm-svn: 162083

[libclang] Add a flag to create the precompiled preamble on the first parse. Summary: The current default is to create the preamble on the first reparse, aka second parse. This is useful for clients that do not want to block when opening a file because serializing the preamble takes a bit of time. However, this makes the reparse much more expensive and that may be on the critical path as it's the first interaction a user has with the source code. YouCompleteMe currently optimizes for the first code interaction by parsing the file twice when loaded. That's just unnecessarily slow and this flag helps to avoid that.
