[Bug c/23067] New: Incorrect struct layout on darwin

[sabre at nondot dot org]

The Darwin ABI specifies that this struct should be 12 bytes in size and have 4-byte alignment.  Current 
mainline gives it 8-byte alignment and 16-byte size.

struct ULL {
  int X; long long Y;
};
ULL *ULLSize(ULL *ARG, int *P) { *P = sizeof(ULL); return ARG+1; }

In general, the special cases in the alignment hooks are special cased to handle DFmode elements,  but 
should include DImode values as well.
