PR tree-optimization/89280
* tree-cfgcleanup.c (maybe_dead_abnormal_edge_p,
builtin_setjmp_setup_bb): New functions.
(cleanup_control_flow_pre): Ignore maybe_dead_abnormal_edge_p edges.
When visiting __builtin_setjmp_setup block, queue in special
setjmp_vec vector edges from .ABNORMAL_DISPATCHER to corresponding
__builtin_setjmp_receiver. Remove .ABNORMAL_DISPATCHER basic blocks
from visited after the loop if they don't have any visited successor
blocks.
* gcc.c-torture/compile/pr89280.c: New test.
* gcc.dg/torture/pr57147-2.c: Don't expect a setjmp after noreturn
function. Skip the test for -O0.
