Summary: Add usage count to find-all-symbols. FindAllSymbols now finds (most!) main-file usages of the discovered symbols. The per-TU map output has NumUses=0 or 1 (only one use per file is counted). The reducer aggregates these to find the number of files that use a symbol. The NumOccurrences is now set to 1 in the mapper rather than being inferred by the reducer, for consistency. The idea here is to use NumUses for ranking: intuitively number of files that use a symbol is more meaningful than number of files that include the header.
