        PR tree-optimization/51070
        * tree-loop-distribution.c (generate_builtin): Do not replace
        the loop with a builtin if the partition contains statements which
        results are used outside of the loop.
        (stmt_has_scalar_dependences_outside_loop): Properly handle calls.

        * gcc.dg/torture/pr51070.c: New testcase.
        * gcc.dg/torture/pr51070-2.c: Likewise.
