Add SPU optimized scalar math functions for functions that are based on
the SPU SIMD math headers.

The header files of the form spu/headers/*{d2,f4}.h are imported as-is
from the SDK SIMD math source.

Scalar headers include the SIMD header, and in turn the scalar headers are
included by the .c files. For example, s_tan.c includes headers/tan.h, and
tan.h includes headers/tand2.h, and the bulk of the code is (generally) in
tand2.h.
