The mentioned flag is already both a cc1 & driver flag; however, whether it is respected was tied to either: 1. Whether it was passed as a cc1 option (`Xclang`) 2. or `-fmodules` accompanying it This poses a consistency problem where `std=c++20` enables the modules feature, independent of other module settings. This patch resolves this issue by checking for the presence unconditionally & passing it down to cc1 when applicable.
