removed some x86 intrinsic functions that were in the mat44_impl file reinstated some mMath_C functions and mMathFn ptrs trying to diagnose an issue. Had to come up with a different way to initialize the scalar table if the isa tables are not initialized yet. Mac did not like the static initialization. Had to change neon over to using explicit masks for shifting, cross product was failing during bakes and matrix calculations
