        * tree.h (DECL_COMPLEX_GIMPLE_REG_P): Rename to ...
        (DECL_GIMPLE_REG_P): This.
        * fold-const.c (fold_indirect_ref_1): Fold *(foo *)&vectorfoo into
        using BIT_FIELD_REF.
        * omp-low.c (omp_copy_decl_2): Use the renamed DECL_GIMPLE_REG_P.
        * tree-gimple.c (is_gimple_reg): Use the renamed DECL_GIMPLE_REG_P
        and check for VECTOR_TYPE.
        * expr.c (get_inner_reference): Set the mode for BIT_FIELD_REF with
        vector types.
        * tree-flow-inline.h (var_can_have_subvars): Use the renamed
        DECL_GIMPLE_REG_P.
        * gimplify.c (internal_get_tmp_var): Use the renamed DECL_GIMPLE_REG_P
        and check for VECTOR_TYPE.
        (gimplify_bind_expr): Likewise.
        (gimplify_function_tree): Likewise.
        * expmed.c: Include target.h.
        (extract_bit_field): For vector mode, try find a better mode first.
        If that fails use gen_lowpart (for vectors only).

        and check for VECTOR_TYPE.

        (insert_fake_stores): Create gimple register store_tmps for
        vector types.
        * tree-sra.c (sra_elt): New field, is_vector_lhs.
        (sra_walk_expr <case BIT_FIELD_REF>): For vector types that
        are the left hand side, set the element's is_vector_lhs to true.
        (instantiate_element): For vector types which were on the left         hand size, set DECL_GIMPLE_REG_P to false.
        * tree-nested.c (create_tmp_var_for): Use the renamed DECL_GIMPLE_REG_P.        * tree-inline.c (declare_return_variable):  Use the renamed
