Fix double warning about illegal floating-point literal pattern
This PR fixes#86600. The problem is that the `ConstToPat` struct contains a field `include_lint_checks`, which determines whether lints should be emitted or not, but this field is currently not obeyed at one point, leading to a warning being emitted more than once. I have fixed this behavior here.
Account for capture kind in auto traits migration

2229: Reduce the size of closures with `capture_disjoint_fields`
One key observation while going over the closure size profile of rustc
was that we are disjointly capturing one or more fields starting at an
immutable reference.
Disjoint capture over immutable reference doesn't add too much value
because the fields can either be borrowed immutably or copied.
One possible edge case of the optimization is when a fields of a struct
have a longer lifetime than the structure, therefore we can't completely
get rid of all the accesses on top of sharef refs, only the rightmost
one. Here is a possible example:
```rust
struct MyStruct<'a> {
a: &'static A,
b: B,
c: C<'a>,
}
fn foo<'a, 'b>(m: &'a MyStruct<'b>) -> impl FnMut() + 'static {
let c = || drop(&*m.a.field_of_a);
// Here we really do want to capture `*m.a` because that outlives `'static`
// If we capture `m`, then the closure no longer outlives `'static'
// it is constrained to `'a`
}
```

- Add `:Sized` assertion in interpreter impl
- Use `Scalar::from_bool` instead of `ScalarInt: From<bool>`
- Remove unneeded comparison in intrinsic typeck
- Make this UB to call with undef, not just return undef in that case
special case for integer log10
Now that #80918 has been merged, this PR provides a faster version of `log10`.
The PR also adds some tests for values close to all powers of 10.
Document rustdoc with `--document-private-items`
The `tool_doc` macro introduced in #86737 did not use `false` as the default value for `binary` when it is not provided, so the `if` is not even expanded and thus the argument is never provided if the `binary` argument isn't.
Resolves#86900

Checking that function is const if marked with rustc_const_unstable
Fixes#69630
This one is still missing tests to check the behavior but I checked by hand and it seemed to work.
I would not mind some direction for writing those unit tests!
Update BTreeSet::drain_filter documentation
This commit makes the documentation of `BTreeSet::drain_filter` more
consistent with that of `BTreeMap::drain_filter` after the changes in
f0b8166870.
In particular, this explicitly documents the iteration order.
Use diagnostic items instead of lang items for rfc2229 migrations
This PR removes the `Send`, `UnwindSafe` and `RefUnwindSafe` lang items introduced in https://github.com/rust-lang/rust/pull/84730, and uses diagnostic items instead to check for `Send`, `UnwindSafe` and `RefUnwindSafe` traits for RFC2229 migrations.

BTree: consistently avoid unwrap_unchecked in iterators
Some iterator support functions named `_unchecked` internally use `unwrap`, some use `unwrap_unchecked`. This PR tries settling on `unwrap`. #86195 went up the same road but travelled way further and doesn't seem successful.

Support pretty printing slices using GDB
Support pretty printing `&[T]`, `&mut [T]` and `&mut str` types using GDB.
Support pretty printing `&mut [T]` and `&mut str` types using LLDB.
Fixes#85219.
At least one of these is already in-tree; it seems plausible that
others might appear too.
