re PR middle-end/56443 (internal compiler error: verify_gimple failed at -O[1-2] -ftree-vectorize)
PR tree-optimization/56443
* tree-vect-stmts.c (get_vectype_for_scalar_type_and_size): For
overaligned types, pass TYPE_UNSIGNED (scalar_type) as second argument
to type_for_mode langhook.
* gcc.dg/torture/pr56443.c: New test.
