[committed] Add check_vect in a testcase

[Matthew Malcomson via Gcc-patches]

Also reformat a comment that had too long lines.
Commit c5bd0e5870a introduced both these problems to fix.

Committed as obvious after ensuring that when running the testcase on
AArch64 it still fails before the original c5bd0e5870a commit and passes
after it.

gcc/ChangeLog:

        * tree-vect-stmts.cc (get_group_load_store_type): Reformat
        comment.

gcc/testsuite/ChangeLog:

        * gcc.dg/vect/vect-multi-peel-gaps.c: Add `check_vect` call into
        `main` of this testcase.
