I thought that the rest of the compiler just appends to the `Path` we pass in
here. But looking into that a bit closer I see that `pruneModuleCache()` in
`CompilerInstance.cpp` calls `llvm::sys::path::native()` on this and
`HeaderSearch::getCachedModuleFileNameImpl()` calls
`llvm::sys::fs::make_absolute()`. I'll investigate if these are necessary and
if so, I'll try to unify things so that just doing string prefix match is
enough in all situations.
