For debug info quality it actually isn't just about using different
SSA_NAME, but also not reusing the defining stmt; only then the code
will magically try to create debug temporaries and expressions from the old
dead defining stmt.

I've added some comments and one assert (that the uids are non-zero).
Because of that assertion I'll bootstra

I've spent over two days looking at reassoc, fixing spots where

Hi!
I've spent over two days looking at reassoc, fixing spots where
we invalidly reused SSA_NAMEs (this results in wrong-debug, as the added
guality testcases show, even some ICEs (pr58791-3.c) and wrong range info
for SSA_NAMEs) and cleaning up the stmt scheduling stuff (e.g. all gsi_move*
