re PR middle-end/79805 (ICE (verify_flow_info failed) with -fnon-call-exceptions -O)
PR middle-end/79805
* internal-fn.def (ATOMIC_BIT_TEST_AND_SET, ATOMIC_BIT_TEST_AND_RESET,
ATOMIC_BIT_TEST_AND_COMPLEMENT, ATOMIC_COMPARE_EXCHANGE): Remove
ECF_NOTHROW.
* gimple-fold.c (fold_builtin_atomic_compare_exchange): Set
gimple_call_nothrow_p flag based on whether original builtin can throw.
If it can, emit following stmts on the fallthrough edge.
* tree-ssa-ccp.c (optimize_atomic_bit_test_and): Similarly, except
don't create new bb if inserting just debug stmts on the edge, try to
insert them on the fallthru bb or just reset debug stmts.
* g++.dg/opt/pr79805.C: New test.
