The following fixes an omission in r14-162-gcda246f8b421ba causing
wrong-debug and a bunch of guality regressions.

Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

	PR tree-optimization/109596
	* tree-ssa-loop-ch.cc (ch_base::copy_headers): Propagate
	debug stmts to nonexit->dest rather than exit->dest.
