  Log Message:
  -----------
  [clang driver] Move default module cache from system temporary directory

1) Shared writable directories like /tmp are a security problem.
2) Systems provide dedicated cache directories these days anyway.
3) This also refines LLVM's cache_directory() on Darwin platforms to use
   the Darwin per-user cache directory.
