    [debug] introduce precise binary code coverage. · d71ef941
    yangguo authored
    With precise binary code coverage, the reported count is either 0 or 1.
    We only report 1 the first time we collect coverage data after the
    function has been executed.
    
    Since we do not care about the accurate execution count, we can optimize
    the function once it has been executed once.
    
    Also change best effort coverage to be implicitly binary.
