[Bug c/17322] New: initializer folding broken

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Recent changes to the handling of structure references for C have broken
the folding of some valid initializers.

struct s { int a; int b[1]; };
struct s x;
int *y = ((struct s *)&x.a)->b;

involves a valid address constant, but is now wrongly rejected with

t.c:3: error: initializer element is not constant
