I have been doing that even before clang had a VFS.

The idea is using cmake to put the content of the file in the binary

Using this cmake script
https://github.com/woboq/moc-ng/blob/master/src/CMakeLists.txt#L57
and
https://github.com/woboq/moc-ng/blob/master/src/embedded_includes.h.in
This puts the file contents into the binary

Then I added a "-I/builtins" to the command line, and used 
ToolInvocation::mapVirtualFile to expose the files:
