// The main library imports lib1 and lib2 deferred and use lib1.foo1 and
// lib2.foo2. This should trigger seperate outputunits for main, lib1 and lib2.
// Both lib1 and lib2 import lib3 directly and
// both use lib3.foo3. Therefore a shared output unit for lib1 and lib2 should
// be created.
// lib1 and lib2 also import lib4 deferred, but lib1 uses lib4.bar1 and lib2
// uses lib4.bar2. So two output units should be created for lib4, one for each
// import.
