Make shader math functions SIMD width agnostic

This change replaces explicit 4-wide vectors with their SIMD
counterpart. Currently these sw::SIMD types still alias to packed 4-wide
vector types, but these aliases will be changed to rr::SIMD types in a
subsequent change.

Functions such Sqrt<>, Pow<>, reciprocal(), halfToFloatBits() etc. are
not changed at this time because we have code paths with use packed
4-wide vector arguments, as well as SIMD types. These functions will be
split up in a subsequent change.
