[Bug tree-optimization/68786] Aligned masked store is generated for unaligned pointer

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68786 --- Comment #3 from Jakub Jelinek --- For normal vectorized stores, the alignment is preserved through the MEM_REF/TARGET_MEM_REF type, e.g. 5991 TREE_TYPE (data_ref) 5992= build_aligned_type

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68707 --- Comment #6 from alalaw01 at gcc dot gnu.org --- Well, I can confirm that the patch generates load-lanes/store-lanes instead of SLP, all over the (vect) testsuite. All execution tests are passing :) so it *may* just be a case of updating a lot
