fe3e8e402b (left_shift_overflows, same_sign, overflow_sum_sign): New macros. 
(add_double, div_and_round_double, lshift_double, mul_double):
(neg_double, const_binop, fold): Check for signed integer overflow.
Propagate overflow flags from operands to result.
(const_binop, fold_convert): Use pedwarn for overflow warnings.
Say `constant expression', not `constant folding', for user's sake.

b8eb43a245 (fold): Move conversion back outside of COND_EXPR if moving it inside 
didn't help anything.

(div_and_round_double): Change some more ints to HOST_WIDE_INTs.

(operand_equal_p): Make it clear that this function
tests for indistinguishable values, not for equality as computed by
`=='; the distinction is important for IEEE NaNs and -0.0.

b5c525860d (fold): Don't fold (A op B ? A : C) if A is IEEE 
floating point, because A might be -0.0 or NaN.

c0b9d4c816 (optimize_bit_field_compare): Correct bogus use of types in expressions... 
(optimize_bit_field_compare): Correct bogus use of types in
expressions; always do computation in a type wide enough for the
result.
