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.

PR tree-optimization/103816
* 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.

Note the access to 'g' makes it larger than half of the address space which
makes the program ill-formed.
