Implement lane-independent SIMD operations

This change implements all operations for SIMD::Int, SIMD::UInt, and
SIMD::Float which operate independently on each lane (including
broadcast).

While the types are defined within the SIMD namespace, the operators
are not. This allows one to write explicitly SIMD code while within the
rr namespace. The scalar namespace aliases the rr::Int, UInt, and Float
types, to easily discern them from the SIMD types by the same name and
access them from within the SIMD namespace without using the less
explicit rr namespace.
