Pull in r156591 from upstream llvm trunk:

Allow unique_file to take a mode for file permissions, but default
  to user only read/write.

and r156592 from upstream clang trunk:

  For final output files create them with mode 0664 to match other
  compilers and expected defaults.

This should fix clang creating files with mode 0600.
