internal/core/compile: separate out phase of let clauses

This allows referring to lets later in scope, as the spec allows.

By hindsight, a better mechanism would be to treat lets as
arcs with special handling. This will preserve formatting
information and will obviate the need for special caching
to avoid exponential blowup.

This can be done as an overall rework of making Vertex
processing linear, instead of the current O(n^2).
