I tried to construct a testcase for __restrict__ case:

Richard,
thanks, I also think alias trick makes gloal vars safe for merging across
RESTRICT flags.
One however needs to consider merging of items referring restricted vars.
const restrict int *a=&var;

Ok, as variable merging always creates aliases accesses and their types remain
the same. So we don't need any extra checks for merging globals here.

Hi,
while looking for a testcase that would trigger with tree-tail-merge (because
gimple-fold seems to also miss MEM_REF merging) I noticed following oddity:
struct a
{
int a[10];
};
typedef struct a b

Thanks for looking into this! I think this was just the most obvoious of TYPE
flags. Some more we need to look into:
Is the alias class compare enough to handle TYPE_RESTRICT?
We probably want to match TYPE_A
