Auto merge of #88242 - bonega:allocation_range, r=oli-obk
Use custom wrap-around type instead of RangeInclusive Two reasons: 1. More memory is allocated than necessary for `valid_range` in `Scalar`. The range is not used as an iterator and `exhausted` is never used. 2. `contains`, `count` etc. methods in `RangeInclusive` are doing very unhelpful(and dangerous!) things when used as a wrap-around range. - In general this PR wants to limit potentially confusing methods, that have a low probability of working. Doing a local perf run, every metric shows improvement except for instructions. Max-rss seem to have a very consistent improvement. Sorry - newbie here, probably doing something wrong.
