Rollup merge of #40576 - dwrensha:mir-terminator-kind-doc-typo, r=nikomatsakis
fix innacuracy in mir TerminatorKind::SwitchInt docs

Each index of `values` corresponds to an index of `targets`, and `targets` additionally has a "default case" element at its end, so `targets.len() == values.len() + 1`, not the other way around. For example, [here](https://github.com/rust-lang/rust/blob/0aeb9c12979e6da753701a798d04105b6b1a8c28/src/librustc/mir/mod.rs#L549-L550) is a concrete instance of `SwitchInt` being constructed with `targets.len() == 2` and `values.len() == 1`.
