[Bug tree-optimization/108751] Removing dead code results in worse generated target code at -Os

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108751 --- Comment #1 from Theodoros Theodoridis --- I am not sure if this qualifies as a "bug"/missed optimization but I'd be interested in understanding why these changes cause such a difference. Thanks!
