Zalathar a1e2c10b1f coverage: Simplify building coverage expressions based on sums
In some cases we need to prepare a coverage expression that is the sum of an
arbitrary number of other terms. This patch simplifies the code paths that
build those sums.

This causes some churn in the mappings, because the previous code was building
its sums in a somewhat idiosyncratic order.
