enforce user annotations in closure signatures
Not *quite* ready yet but I'm opening anyway. Still have to finish running tests locally.
Fixes#54692Fixes#54124
r? @matthewjasper
This fixes `issue-28848.rs` -- it also handles another case that the
AST region checker gets wrong (`wf-self-type.rs`). I don't actually
think that this is the *right way* to be enforcing this constraint --
I think we should probably do it more generally, perhaps by editing
`predicates_of` for the impl itself. The chalk-style implied bounds
setup ought to fix this.
#45829 when a renamed import conflict with a previous import
Fix the suggestion when a renamed import conflict.
It check if the snipped contains `" as "`, and if so uses everything before for the suggestion.
[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.

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.
