This flag implies `-ivfsoverlay`, and additionally passes the same argument to the linker if it supports it. At present the only linker which does is lld-link, so this functionality has only been added to the MSVC toolchain. Additionally this option has been made a CoreOption so that clang-cl can use it without `-Xclang` Differential Revision: https://reviews.llvm.org/D141808
