On Darwin platforms, this fixes the following problem: indexstore-db by itself returns realpaths but the build system might be using standardized Darwin paths (eg. realpath is `/private/tmp` but the standardized path is `/tmp`). Because of this, when inferring the main file for a file, we might get a URI that the build system doesn’t know about. To fix this, if the realpath that indexstore-db returns could not be found in the build system's source files but the standardized path is part of the source files, use the standardized path instead.
