<pre>Testcase:
```
struct X { ~X(); int c; };
extern int n;
X *p = new X[n];
void f() { delete [] p; }
```
On x86_64, under `-faligned-new=2`, this passes `align_val_t{8}` to `operator
new[]` but passes `align_val_t{4}` to `operator delete[]`.
Presumably we should consistently either always or never take the array
cookie's alignment into account when synthesizing the `align_val_t` argument;
always taking it into account seems like the better choice.</pre>
