    tree-optimization/113073 - amend PR112736 fix

    The PR112736 testcase fails on RISC-V because the aligned exception
    uses the wrong check.  The alignment support scheme can be
    dr_aligned even when the access isn't aligned to the vector size
    but some targets are happy with element alignment.  The following
    fixes that.

            * tree-vect-stmts.cc (vectorizable_load): Properly ensure
            to exempt only vector-size aligned overreads.=
