Simple SSE and SSE2 optimized sin, cos, log and exp

Simple SSE and SSE2 (and now NEON) optimized sin, cos, log and exp The story I have spent quite a while looking for a simple (but fast) SSE version of some basic transcendental functions (sines and exponential). On the mac, you get the vsinf and friends (in the Accelerate framework) which are nice (there is a ppc version and an intel version, Apple rox) but closed-source, and restricted to macos..

also ARM version. Note: there's a faster exp implementation.
