        * tree-vect-stmts.c (vectorizable_simd_clone_call): Handle
        SIMD_CLONE_ARG_TYPE_LINEAR_REF_CONSTANT_STEP like
        SIMD_CLONE_ARG_TYPE_LINEAR_CONSTANT_STEP.  Add
        SIMD_CLONE_ARG_TYPE_LINEAR_VAL_CONSTANT_STEP and
        SIMD_CLONE_ARG_TYPE_LINEAR_UVAL_CONSTANT_STEP cases explicitly.

        * semantics.c (finish_omp_clauses) <case OMP_CLAUSE_LINEAR>:
        For OMP_CLAUSE_LINEAR_REF don't require type to be
        integral or pointer.

        * g++.dg/vect/simd-clone-6.cc: New test.
        * g++.dg/gomp/declare-simd-6.C: New test.
