D18551: clang: Create preamble only on second parse

[René J.V. Bertin]

  You don't have control over where those pch files are written, right, other than through setting $TMPDIR?
  
  Because it seems that if that control existed the best solution might be to store the pchs corresponding to the open files in a session in a session-specific cache directory (and trash the ones of files no longer open when you close the session).
