Consider the case of a toolchain that includes clang is being used to compile Swift. With the current ordering, the header will be found relative to that toolchain, which could be out of date as compared to tip. This is the case today if eg. a 5.7 toolchain is used to build main/5.9 as the shim header is missing a definition.
