tree-optimization/103361 - fix unroll-and-jam direction vector handling
This properly uses lambda_int instead of truncating the direction

* gimple-loop-jam.c (adjust_unroll_factor): Use lambda_int
for the dependence distance.
* tree-data-ref.c (print_lambda_vector): Properly print a lambda_int.
* g++.dg/torture/pr103361.C: New testcase.
