* fold-const.c (int_const_binop): Return NULL_TREE when an expression
can't be evaluated at compile-time (instead of calling abort).
Return NULL_TREE for division (and modulus) by zero.
(const_binop): Return NULL_TREE for floating point operators that
aren't handled by real_arithmetic.
(fold_binary): Eliminate "wins" variable, and "binary" label, by
folding operators with constant operands early. Assert that
operands are non-NULL.
