* 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.
