    tree-optimization/108752 - vectorize emulated vectors in lowered form

    The following makes sure to emit operations lowered to bit operations
    when vectorizing using emulated vectors.  This avoids relying on
    the vector lowering pass adhering to the exact same cost considerations
    as the vectorizer.

            PR tree-optimization/108752
            * tree-vect-generic.cc (build_replicated_const): Rename
            to build_replicated_int_cst and move to tree.{h,cc}.
            (do_plus_minus): Adjust.
            (do_negate): Likewise.
            * tree-vect-stmts.cc (vectorizable_operation): Emit emulated
            arithmetic vector operations in lowered form.
            * tree.h (build_replicated_int_cst): Declare.
            * tree.cc (build_replicated_int_cst): Moved from
            tree-vect-generic.cc build_replicated_const.
