Do not ignore failures from gimple_range_calc_op2.

We were ignoring the return value if op2 returned false and getting garbage ranges propagated.

gcc/ChangeLog:

PR tree-optimization/97381
* gimple-range-gori.cc (gori_compute::compute_operand2_range): If a range cannot be
calculated through operand 2, return false.

gcc/testsuite/ChangeLog:

* gcc.dg/pr97381.c: New test.
