Returns the number of eligible matches for the distance.

This will return a list of the number of finite entries in a distance matrix. If the distance has no subgroups, it will be a list of length 1. If the distance has subgroups (i.e. x is an BlockedInfinitySparseMatrix, it will be a named list.)
