i386.md (neg, [...]): Revmap to use ix86_expand_unary_operator and ix86_unary_operator_ok.

        * i386.md (neg, not and abs patterns): Revmap to use
        ix86_expand_unary_operator and ix86_unary_operator_ok.
        (add?f and sub?f expanders): Force operand 1 to register.
        * i386.c (ix86_expand_unary_operator): Rewrite.
        (ix86_unary_operator_ok): Ensure that memory operands
        match real opcode.
        (ix86_binary_operator_ok): Do not allow operand 1 to
        come into memory and operand 0 not.
        (ix86_expand_binary_operator): Ensure that
        src1 is not non-matching memory.
