Log:
        PR rtl-optimization/79780
        * cprop.c (one_cprop_pass): When second and further conditional trap
        in a single basic block is turned into an unconditional trap, turn it
        into a deleted note to avoid RTL verification failures.

        * gcc.c-torture/compile/pr79780.c: New test.
