I think count_while makes a lot of sense given that we have drop- and take-while. But I see that `llvm::StringRef` and `std::string_view` have slightly worse semantics, so I added some find methods similar to `find_if` and `find_if_not` from `llvm::StringRef` and kept count_while only as a helper (since I adopted npos as sentinel return value, similar to the other string ref/view implementations)
