Use a keyword in raw identifier example
That's a very small documentation fix. The text says "you can now use keywords as identifiers" but example didn't use a keyword and would work without raw identifiers.
Felix S. Klock II pointed out that this suggestion (introduced in
pull-request #43178 / eac74104) was being issued for one-field-struct
expected types (in which case it is misleading and outright wrong),
even though it was only intended for one-field enum-variants (most
notably, `Some`). Particularly tender-hearted code-historians may be
inclined to show mercy towards the author of #43178 on the grounds
that it's somewhat confusing that struct field definitions are given
in a type called `ty::VariantDef`.
Add a conditional to adhere to the original intent. (It would be
possible to generalize to structs, but not obviously net desirable.)
This adds a level of indentation, so the diff here is going to be
easier to read in ignore-whitespace mode (`-w`).
Resolves#55250.
The example was not as clear as it could be because it was making an assumption about the structure of the data in order to multiply the number of collection elements by the item size. This change demonstrates the idea more straightforwardly, without the calculation.

[NLL] Use new region infer errors when explaining borrows
Use the new free region infer errors for explaining borrows
This gives at least some explanation for why a borrow is expected to
last for a certain free region. Also:
* Reports E0373: "closure may outlive the current function" with NLL.
* Special cases the case of returning a reference to (or value referencing) a local variable or temporary (E0515).
* Special case assigning a reference to a local variable in a closure to a captured variable. (E0521)
Closes#51026 - `regions-nested-fns-2.rs` isn't changed to that diagnostic, since that would not be the correct error here.
Closes#51169
cc #53882 - The error is (IMO) better now, but it could be better when we trace lifetimes in these error messages.

Update Cargo, build curl/OpenSSL statically via features
In addition to to updating Cargo's submodule and Cargo's dependencies,
this also updates Cargo's build to build OpenSSL statically into Cargo
as well as libcurl unconditionally. This removes OpenSSL build logic
from the bootstrap code, and otherwise requests that even on OSX we
build curl statically.

Adds UseAsConst and UseAsStatic to replace Return in consts/statics.
Don't report the arguments to an overloaded operator as CallArguments.
Also don't report "escaping data" in these items.
