Fix GROUP_GAP for single-element interleaving
vectorizable_load had a curious "force_peeling" variable, with no
comment explaining why we need it for single-element interleaving
but not for other cases. I think it's simply because we weren't
initialising the GROUP_GAP correctly for single loads.
Tested on aarch64-linux-gnu and x86_64-linux-gnu.
gcc/
* tree-vect-data-refs.c (vect_analyze_group_access_1): Set
GROUP_GAP for single-element interleaving.
* tree-vect-stmts.c (vectorizable_load): Remove force_peeling
variable.
