re PR rtl-optimization/79780 (ICE in rtl_verify_bb_insns, at cfgrtl.c:2661 (error: flow control insn inside a basic block))

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.
