        * config/i386/i386.c (ix86_expand_vector_move): Use the mode
        of the operand, rather than assuming TImode.
        (ix86_expand_binop_builtin): Cope with commutative patterns
        using nonimmediate_operand for both operands.
        (ix86_expand_timode_binop_builtin): Likewise.
        (ix86_expand_store_builtin): Validate operand 1.
        (ix86_expand_unop1_builtin): Likewise.
