This moves the computation values need for the lowering to the
inference visitor and passes these to the lowering through fields on
the patterns.
This prepares for performing lowering during constant evaluation.

This stores the matched type, as computed by the flow analysis, into
patterns that use it in their lowering.
This ensures that flow is taken into account in the matching expressions
and also prepares for decoupling the matching expression generation
from the inference visitor.
