[cfe-dev] Random clang testing results

I tried building Blender with clang today for fun. Went without a hitch,
although I had to use gcc for two files from ffmpeg with nasty inline asm.
Blender has about 600k lines of C code internally, and another 600k from
external libraries (like FFTW, ffmpeg, qhull, ...).

Some results from comparing renders on the two binaries are here:

A lot of rendering artifacts, but it is remotely possible this is a Blender
bug not a clang one. Several files show obvious flaws, on the other hand.
