Dennis Gove 2d2582e4f4 SOLR-8559: FCS facet performance optimization
Significantly speeds up processing when terms are high cardinality and the matching docset is small. 
When facet minCount > 0 and the number of matching documents is small (or 0) this enhancement 
prevents considering terms which have a 0 count. Also includes change to move to the next non-zero 
term value when selecting a segment position.
