[cfe-dev] redirect clang warning/error ouput

[mats petersson via cfe-dev]

To a "buffer" (along the lines of `std::stringstream`) is also possible if
you write your own "driver" for the compiler, but clang as an exectuable
file has no concept of "buffer" as output destination.

I'm not going to look up exactly how to do write the necessary code to
capture the output from the compiler components, but I know it's possible,
and there have been posts about it in the past.
