Originally landed in:6400905a61Reverted in:668dccc396Fix branch coverage merging in FunctionCoverageSummary::get() for instantiation groups. This change corrects the implementation for the branch coverage summary to do the same thing for branches that is done for lines and regions. That is, across function instantiations in an instantiation group, the maximum branch coverage found in any of those instantiations is returned, with the total number of branches being the same across instantiations.
