abhinavdangeti 7e36109b3c MB-28162: Provide API to estimate memory needed to run a search query
This API (unexported) will estimate the amount of memory needed to execute
a search query over an index before the collector begins data collection.

Sample estimates for certain queries:
{Size: 10, BenchmarkUpsidedownSearchOverhead}
                                                           ESTIMATE    BENCHMEM

Steve Yen c7a342bc7d scorch conjuncts match phrase test passes
The conjunction searcher Advance() method now checks if its curr
doc-matches suffices before advancing them.

Steve Yen 33687260ca children of conjunct/disjunct's are not necessarily termSearchers
Rename termSearcher loop variable to searcher, as the child searchers
of a conjunction/disjunction searcher aren't necessarily
termSearchers.

Steve Yen 89a1cefde1 API change: optional SearchRequest.IncludeLocations flag
This is a change in search result behavior in that location
information is no longer provided by default with search results.

Although this looks like a wide-ranging change, it's mostly a
mechanical replacement of the explain bool flag with a new
search.SearcherOptions struct, which holds both the Explain bool flag
and the IncludeTermVectors bool flag.
