Brecht Van Lommel e1b3d91127 Refactor: replace Cycles sse/avx types by vectorized float4/int4/float8/int8
The distinction existed for legacy reasons, to easily port of Embree
intersection code without affecting the main vector types. However we are now
using SIMD for these types as well, so no good reason to keep the distinction.

Also more consistently pass these vector types by value in inline functions.
Previously it was partially changed for functions used by Metal to avoid having
to add address space qualifiers, simple to do it everywhere.

Also removes function declarations for vector math headers, serves no real
purpose.
