* simplify-rtx.c (simplify_plus_minus): Remove final parameter.
Always produce an output if we can remove NEGs or canonicalize
(minus (minus ...)) expressions.  Provide a fast path for the
two-operand case.
(simplify_gen_binary): Do not call simplify_plus_minus.
(simplify_binary_operation_1): Reassociate at the end of the
function.
