/// This test validates that modules that depend on prebuilt modules
/// resolve `is-in-stable-directories` correctly.
/// The steps are:
/// 1. Scan dependencies to build the PCH. One of the module's depend on header
/// that is seemingly from the sysroot. However, it depends on a local header that is overlaid.
/// 2. Build the PCH & dependency PCMs.
/// 3. Scan a source file that transitively depends on the same modules as the pcm.
