Store phi variables in a collection of SIMD components

Previously the components of phi variables were stored as Reactor
arrays, but this isn't necessary since phis aren't dynamically
indexable. They can instead be stored as individual components.

This avoids spending time in the scalar-replacement-of-aggregates (SROA)
optimizaton pass.
