No other iterator makes the distinction between an iterator and an iterator adapter
in its summary line, so change it to be consistent with all other adapters.

encode region::Scope using fewer bytes

Now that region::Scope is no longer interned, its size is more important. This PR encodes region::Scope in 8 bytes instead of 12, which should speed up region inference somewhat (perf testing needed) and should improve the margins on #36799 by 64MB (that's not a lot, I did this PR mostly to speed up region inference).

This is a perf-sensitive PR. Please don't roll me up.

r? @eddyb

This is based on  #44743 so I could get more accurate measurements on #36799.

d9d10c1628 Make mir-borrowck more closely match (draft) NLL RFC.
In particular:

 * introduce the shallow/deep distinction for read/write accesses

 * use the notions of prefixes, shallow prefixes, and supporting prefixes
   rather than trying to recreate the restricted sets from ast-borrowck.

 * Add shallow reads of Discriminant and ArrayLength, and treat them
   as artificial fields when doing prefix traversals.

Allow unused extern crate again
This is a partial revert of #42588. There is a usability concern
reported in #44294 that was not considered in the discussion of the PR,
so I would like to back this out of 1.21. As is, I think users would
have a worse and more confusing experience with this lint enabled by
default. We can re-enabled once there are better diagnostics or the case
in #44294 does not trigger the lint.

typeck::check::coercion - roll back failed unsizing type vars

This wraps unsizing coercions within an additional level of
`commit_if_ok`, which rolls back type variables if the unsizing coercion
fails. This prevents a large amount of type-variables from accumulating
while type-checking a large function, e.g. shaving 2GB off one of the
4GB peaks in #36799.

This is a performance-sensitive PR so please don't roll it up.

8a25ec019e Rollup merge of #44103 - zackmdavis:cmp_op_must_use, r=arielb1
add comparison operators to must-use lint (under `fn_must_use` feature)

Although RFC 1940 is about annotating functions with `#[must_use]`, a
key part of the motivation was linting unused equality operators.

(See
https://github.com/rust-lang/rfcs/pull/1812#issuecomment-265695898—it
seems to have not been clear to discussants at the time that marking the
comparison methods as `must_use` would not give us the lints on
comparison operators, at least in (what the present author understood
as) the most straightforward implementation, as landed in #43728
(3645b062).)

To rectify the situation, we here lint unused comparison operators as
part of the unused-must-use lint (feature gated by the `fn_must_use`
feature flag, which now arguably becomes a slight (tolerable in the
opinion of the present author) misnomer).

This is in the matter of #43302.
