D18551: clang: Create preamble only on second parse

[René J.V. Bertin]

  Aaron, don't your arguments apply to parsing an entire project on startup as well? I can easily imagine that opening and parsing entire projects of the size you mention must have a non-negligible cost regardless of all optimisation and caching that is currently implemented
  There is a setting for this feature. A similar switch for the preamble thing will probably be difficult to label comprehensively but maybe a coupling can be made with the full-project-parse switch?
  
  Probably in the sense that you create the preamble on first parse only when not parsing the entire project on import. I'd think that this should maintain the status quo for those files that the user actually opens, while not generating preambles for all the other files.
