Repaired the debug Windows deaths in test_descr, by allocating enough

Browse source 
pad memory to properly align the __dict__ pointer in all cases.

gcmodule.c/objimpl.h, _PyObject_GC_Malloc:
+ Added a "padding" argument so that this flavor of malloc can allocate
  enough bytes for alignment padding (it can't know this is needed, but
  its callers do).

typeobject.c, PyType_GenericAlloc:
+ Allocated enough bytes to align the __dict__ pointer.
+ Sped and simplified the round-up-to-PTRSIZE logic.
+ Added blank lines so I could parse the if/else blocks <0.7 wink>.
