The `BoolFOption` marshalling multiclass should be only used for flags where either the positive or the negative (or both) are -cc1 options and map to a field in `CompilerInvocation`.

Since this patch only deals with the driver (not the cc1 frontend) using `BoolFOption` is not correct. Please, revert this change to the previous state.

I might need to explicitly call this out in the documentation https://clang.llvm.org/docs/InternalsManual.html#adding-new-command-line-option.
