REVISION SUMMARY
  Instead of creating preambles for all files in a project, we only create
  them when a translation unit is parsed for a second time, usually
  because it's edited. The serialization of the preamble takes time, and
  probably doesn't make sense when we throwing it away soon after without
  using it again.

TEST PLAN
  The initial parsing of a project doesn't create any preamble files
  anymore, but they appear when files are edited.

  R32 KDevelop
