Treat undefined operands as varying in GORI.

If the LHS is UNDEFINED simply stop calculating.  Treat op1 and op2
as VARYING if they are UNDEFINED.

PR tree-optimization/103079
gcc/
* gimple-range-gori.cc (gimple_range_calc_op1): Treat undefined as
varying.
(gimple_range_calc_op2): Ditto.

gcc/testsuite/
* gcc.dg/pr103079.c: New.
