Initial commit of cliptest work. More to come shortly.
- Add debug, benchmark code. - Change linux/x86 FAST_MATH code to GCC/x86, and clear FP exceptions before exiting the fast math block. - Remove divide-by-zero test in x86 cliptest, and set clipped vertices to [0,0,0,1] instead of leaving them uninitialized.
