Hi!
Appears that I'm too dumb to implement

..., and implementing proper support for symbol aliases via the nvptx
'ld': <https://gcc.gnu.org/PR105018> "[nvptx] Need better alias support",
won't be complete any time soon, but fortunately there's a way to handle
the cases that we're concerned about here in an even simpler way, for
reasonably modern configurations; any comments before I push the attached
"nvptx: In offloading compilation, special-case certain host-setup symbol aliases
[PR101544]"?
In particular, is the use of a new 'c++ cdtor alias' attribute OK?
Hmm, seems weird to use aliases in that one case but not others. If
you're going to use aliases, why not just turn on alias support?
If aliases aren't supported, I think you want to fix can_alias_cdtor to
return false.
