Rollup merge of #139909 - oli-obk:or-patterns, r=BoxyUwU
implement or-patterns for pattern types

These are necessary to represent `NonZeroI32`, as the range for that is `..0 | 1..`. The `rustc_scalar_layout_range_*` attributes avoided this by just implementing wraparound and having a single `1..=-1` range effectively. See https://rust-lang.zulipchat.com/#narrow/channel/481660-t-lang.2Fpattern-types/topic/.60or.20pattern.60.20representation.20in.20type.20system/with/504217694 for some background discussion
