This is an enhancement to LLVM Source-Based Code Coverage in clang to track how many times individual branch-generating conditions are taken (evaluate to TRUE) and not taken (evaluate to FALSE). Individual conditions may comprise larger boolean expressions using boolean logical operators. This functionality is very similar to what is supported by GCOV except that it is very closely anchored to the ASTs. Differential Revision: https://reviews.llvm.org/D84467
