[libcxx] Tired of colorless compile errors? Enable color diagnostics today!
Summary:
This patch adds a lit option to enable color diagnostics when either `--param=color_diagnostics` is passed to LIT or `LIBCXX_COLOR_DIAGNOSTICS` is present in the environment.
My only concern with this patch is that GCC and Clang take different flags and that only GCC 4.9 and greater support `-fdiagnostics-color=always`
Does anybody have objections to this going in?
