This testcase implements a somewhat complex dependency chain to stress
test the compiler module resolving.

The dependency tree is:

root
 + mod1
    + mod4
    + mod8
 + mod2
    + mod4
    + mod6
    + mod8
    + mod9
 + mod3
    + mod4
    + mod6
 + mod4
 + mod5
    + mod1
       + mod4
       + mod8
    + mod2
       + mod4
       + mod6
       + mod8
       + mod9
    + mod4
    + mod6
    + mod8
    + mod9
       + mod4
       + mod6
 + mod6
 + mod7
    + mod5
       + mod1
          + mod4
          + mod8
       + mod2
          + mod4
          + mod6
          + mod8
          + mod9
       + mod4
       + mod6
       + mod8
       + mod9
          + mod4
          + mod6
    + mod6
 + mod8
