tree-optimization/103816 - detect offset overflow in SLP group analysis
This makes sure to detect overflow when computing DR_GROUP_GAP
and DR_GROUP_SIZE more thoroughly so artificial testcases like the
added one are not fooling the existing check.

* tree-vect-data-refs.c (vect_analyze_group_access_1): Also
check DR_GROUP_GAP compute for overflow and representability.
* gcc.dg/torture/pr103816.c: New testcase.
