[TCWG-CI] Failure after gcc commit: basepoints/gcc-14-2544-g1d203d4c90a Avoid double profile udpate in try_peel_loop
In CI config tcwg_bootstrap_build/master-aarch64-bootstrap_debug after:
| commit 1d203d4c90adb064edfa9680768d1f83a41f17e0
| Author: Jan Hubicka <jh@suse.cz>

| Avoid double profile udpate in try_peel_loop
|
| try_peel_loop uses gimple_duplicate_loop_body_to_header_edge which subtracts the profile
| from the original loop. However then it tries to scale the profile in a wrong way
| (it forces header count to be entry count).
|
| ... 6 lines of the commit log omitted.
