For #13451 1f97dd7

Small fix to GenericPFCandidateSelector to support multi-threading for possible use by HLT. There should be no change in monitored quantities. #13452 is the 80X version of this PR.

The code change is satisfactory, and Jenkins tests against baseline CMSSW_8_1_X_2016-02-23-2300 show no significant differences, as expected.
