[dmd-internals] module .ctors

[Martin Nowak]

Walter, can you remember what the additional return instruction in front  
of the module info ctor is for.

         /*      ret
          * codeOffset:
          *      pushad
          *      mov     EAX,&ModuleReference
          *      mov     ECX,_DmoduleRef
          *      mov     EDX,[ECX]
          *      mov     [EAX],EDX
          *      mov     [ECX],EAX
          *      popad
          *      ret
          */

After relocation in a shared library the ctor entry points to the first  
ret instruction (probably due to alignment?) instead of codeOffset. Is  
this a hack to disable certain modules?
