This solves the problems that D85036 <https://reviews.llvm.org/D85036> tried to solve, but that patch introduced
new bugs and those bugs should be fixed in the clang coverage rather than
llvm-cov. I'll revert D85036 <https://reviews.llvm.org/D85036> after this is landed to avoid reintroduce the bugs.
