0e88db7db4 Dogfood {exclusive,half-open} ranges in compiler (nfc) 
In particular, this allows us to write more explicit matches that
avoid the pitfalls of using a fully general fall-through case, yet
remain fairly ergonomic. Less logic is in guard cases, more is in
the actual exhaustive case analysis.

No functional changes.

78307d8700 Auto merge of #77278 - camelid:use-correct-article, r=estebank 
Use correct article in help message for conversion or cast

Before it always used `an`; now it uses the correct article for the type.

3eab21e22d Don't ICE if called with a TyKind::Error 
It felt too harsh to estebank and others to ICE even though it's
technically a mistake to show a `TyKind::Error`.

dc183702da Replace tuple of infer vars for upvar_tys with single infer var 
This commit allows us to decide the number of captures required after
completing capture ananysis, which is required as part of implementing
RFC-2229.

f52b2d8890 Avoid cycle in nested obligations for object candidate 
Bounds of the form `type Future: Future<Result=Self::Result>` exist in
some ecosystem crates. To validate these bounds for trait objects we
need to normalize `Self::Result` in a way that doesn't cause a cycle.

a6ff925f8b Reduce boilerplate with the matches! macro 
Replaces simple bool `match`es of the form

    match $expr {
        $pattern => true
        _ => false
    }

and their inverse with invocations of the matches! macro.

aa25f9ebd8 Rollup merge of #75099 - davidtwco:is-zst-abstraction-violation, r=eddyb 
lint/ty: move fns to avoid abstraction violation

This PR moves `transparent_newtype_field` and `is_zst` to `LateContext` where they are used, rather than being on the `VariantDef` and `TyS` types, hopefully addressing @eddyb's concern [from this comment](https://github.com/rust-lang/rust/pull/74340#discussion_r456534910).
