Fixing Windows buildbot by not using "BuildTemporaries/module.modulemap" because it is interpreted as defining a module in "BuildTemporaries" directory. Fix errors like > module 'MultiPath' is defined in both 'path/to/modules.cache/3JR48BPRU7BCG/MultiPath-1352QHUF8RNMU.pcm' and 'path/to/modules.cache/3JR48BPRU7BCG/MultiPath-20HNSLLIUDDV1.pcm' To avoid building extra identical modules `-ivfsoverlay` option is not a part of the hash like "/3JR48BPRU7BCG/". And it is build system's responsibility to provide `-ivfsoverlay` options that don't cause observable differences. We also need to make sure the hash like "-1352QHUF8RNMU" is not affected by `-ivfsoverlay`. As this hash is defined by the module map path, use the path prior to any VFS remappings. rdar://111921464 Differential Revision: https://reviews.llvm.org/D156749
