[Bug tree-optimization/26421] tree-ssa-alias.c:find_used_portions considers foo(&var) use all elements of var

Really for this example:
For this case V_MAY_DEF's are dead anyways at least for the other SFT's besides
the one for a.i.

Try thinking what about:
typedef struct {
  int i;
  int j;
  int k;
} Foo;

void bar(Foo*);
void bar1(Foo);
void foo(void)
{
  Foo a;
  a.i = 1;
  bar(&a);
  bar1(a);
}
