compensating for super classes). This was making the reported class
sizes for empty classes very, very wrong.
 - Also, we now report the size info for an empty class like gcc (as
   the offset of the start, not as 0, 0).

   field at end of struct, for example).

static __inline__ __attribute__((always_inline)) 
int bar(int x) { return 4; }
int main() { 
  int X = bar(4);
  printf("%d\n", X);
}

clang was not outputing any debug info for the body of main().  This is
because the backend is getting confused by the region_start/end that clang
is emitting for block scopes.  For now, just disable these (matching llvm-gcc),
this stuff is in progress of rework anyway.
