[SCEV] Introduce SCEVUse, use it instead of const SCEV * (NFCI). (#91961) ...

This patch introduces SCEVUse, which is a tagged pointer containing the
used const SCEV *, plus extra bits to store NUW/NSW flags that are only
valid at the specific use.

This was suggested by @nikic as an alternative
to https://github.com/llvm/llvm-project/pull/90742.

This patch just updates most SCEV infrastructure to operate on SCEVUse
instead of const SCEV *. It does not introduce any code that makes use
of the use-specific flags yet which I'll share as follow-ups.
