Clang static analysis builds should use C runtime directly.

This is a little macro magic to use malloc() directly instead of SDL_malloc(),
etc, so static analysis tests that know about the C runtime can function
properly, and understand that we are dealing with heap allocations, etc.

This changed our static analysis report from 5 outstanding bugs to 30.

5x as many bugs were hidden by SDL_malloc() not being recognized as malloc()
by the static analyzer!
