rust-lang/rust#27282 : Add StatementKind::ReadForMatch
to MIR.
...
(This is just the data structure changes and some boilerplate match
code that followed from it; the actual emission of these statements
comes in a follow-up commit.)

Debug flag to bypass restriction of mutation in match guards.
...
Now, if you pass `-Z disable-ast-check-for-mutation-in-guard`, then we
will just allow you to mutably-borrow and assign in guards of `match`
arms.
This is wildly unsound with AST-borrowck. It is also unsound with
MIR-borrowck without further adjustments, which come in later in the
commit series on this Pull Request.
See also rust-lang/rust#24535 and rust-lang/rfcs#1006 .

Pass a Layout
to oom
...
As discussed in
https://github.com/rust-lang/rust/issues/49668#issuecomment-384893456
and subsequent, there are use-cases where the OOM handler needs to know
the size of the allocation that failed. The alignment might also be a
cause for allocation failure, so providing it as well can be useful.

extend from_raw_parts docs for slices and strs to mention alignment requirement
The documentation for `str::from_raw_parts_mut` seems to not be visible because that method is private, bit I figured it could still be fixed. I also removed the reference to the no-longer-existing `str::from_raw_parts` while I was at it.
Alternatively, should I remove `str::from_raw_parts_mut` completely? it is only used in `str::split_at_mut`, where it might as well be inlined.

operate on `HirId` instead of `NodeId` in `hir::Pat::each_binding`, and consequences of that
See #50928 for motivation.
Questions—
* Is #50928 actually a good idea as a plan of record, or is there some reason to keep `NodeId`s?
* Are the uses of `find_node_for_hir_id` in this initial submission OK (see the FIXME comments)?
* Can we bikeshed a better method names `struct_span_lint_hir` _&c._? (Coined in analogy to the `struct_span_lint_node` and `NodeId`, but it feels kind of semantically clunky.)
