This implements a set of vectorized math routines to be used by the compiler auto-vectorizer. Versions for vectors with 2 lanes up to 64 lanes (in powers of 2) are provided. These routines are based on the scalar versions of the math routines in libm/common, libm/math and libm/mathfp. They make extensive use of the GCC C vector extensions and GCN-specific builtins in GCC.
