Implement range-op entry for __builtin_copysign.
copysign(MAGNITUDE, SIGN) is implemented as the absolute of MAGNITUDE,
with SIGN applied. If the sign of "SIGN" cannot be determined, we
return a range of [-MAGNITUDE, +MAGNITUDE].
gcc/ChangeLog:
* gimple-range-op.cc (class cfn_copysign): New.
(gimple_range_op_handler::maybe_builtin_call): Add
CFN_BUILT_IN_COPYSIGN*.
