MORE MEMORY SANITY

Move the logic tracking which points have been visited already
(including the std::set datastructure) into the indexed query codepaths,
rather than inside accumulators.  This has the effect of drastically
reducing the memory used in non-indexed queries, such that the working
set for a 500-file database with 100000 vectors total goes from 1.2GB to
slightly under 3MB.

All this and less code, too!
