Description Matt Morehouse 2018-02-16 15:52:40 PST 
When building with SanitizerCoverage, simplifyCFG reduces the coverage signal available to libFuzzer when trying to find new inputs.  We need a way to disable simplifyCFG when building with libFuzzer.

See https://github.com/google/sanitizers/issues/893.
