`BindingAnnotation` refactor
* `ast::BindingMode` is deleted and replaced with `hir::BindingAnnotation` (which is moved to `ast`)
* `BindingAnnotation` is changed from an enum to a tuple struct e.g. `BindingAnnotation(ByRef::No, Mutability::Mut)`
* Associated constants added for convenience `BindingAnnotation::{NONE, REF, MUT, REF_MUT}`
One goal is to make it more clear that `BindingAnnotation` merely represents syntax `ref mut` and not the actual binding mode. This was especially confusing since we had `ast::BindingMode`->`hir::BindingAnnotation`->`thir::BindingMode`.
I wish there were more symmetry between `ByRef` and `Mutability` (variant) naming (maybe `Mutable::Yes`?), and I also don't love how long the name `BindingAnnotation` is, but this seems like the best compromise. Ideas welcome.

Don't duplicate file descriptors into stdio fds
Ensures that file descriptors are never duplicated into the stdio fds even if a stdio fd has been closed.
Revert "Mention rust-analyzer maintainers when `proc_macro` bridge is changed"
Reverts rust-lang/rust#99183
rust-analyzer is now a subtree, and CI fails when the `proc_macro` bridge changes break our tests, so these notifications aren't needed anymore.
Add a Machine hook for inline assembly
I'm sketching out some support in Miri to "execute" inline assembly. I want this because there are codebases which have very simple inline assembly like hand-written syscall wrappers, and it would be nice to test such code without modification.

Add let else drop order tests
Add a systematic matrix based test that checks temporary drop order in various settings, `let-else-drop-order.rs`, as requested [here](https://github.com/rust-lang/rust/pull/93628#issuecomment-1055738523).
The drop order of let and let else is supposed to be the and in order to ensure this, the test checks that this holds for a number of cases.
The test also ensures that we drop the temporaries of the condition before executing the else block.
cc #87335 tracking issue for `let else`
The drop order of let and let else is supposed to be the same,
and in order to ensure this, the test checks that this holds for
the given list of cases.
The test also ensures that we drop the temporaries of the
condition before executing the else block.
We made the test matrix based so it can check all the possible
combinations and find out possible edge cases.

Don't suggest reborrow if usage is inside a closure
I can't think of why we would ever be able to *successfully* suggest a mutable reborrow `&mut *` due to a move happening due to a closure, so just suppress it.
Fixes#101119
Suggest `{Option,Result}::{copied,clone}()` to satisfy type mismatch
Fixes#100699, but in the opposite direction (instead of suggesting to fix the signature, it fixes the body)
