bosnichd ff4529fc60 Terrain ray cast benchmarks and optimization. (#7303) ... * Terrain ray cast benchmarks and optimization: - Added some benchmarks that exercise terrain ray casting. - Optimized terrain ray casting by removing an unnecessary AABB intersection check (this was suggested by @invertednormal in the original review, but I forgot to actually remove it until now). - Fixed a bug where we were not normalizing the ray direction before performing the Moller-Trumbore ray<->triangle intersection calculations. Signed-off-by: bosnichd <bosnichd@amazon.com> * Update to make work with changes pulled down from mainline. Signed-off-by: bosnichd <bosnichd@amazon.com>		4 years ago
