Refactor: Rename db locals to diag 
https://github.com/rust-lang/rust/pull/64272 replaced
`DiagnosticBuilder` with `Diagnostic` in some places. This commit just
renames the DB variable from `db` to `diag` where it wasn't renamed.

Rollup merge of #65415 - petrochenkov:rmtest, r=varkor 
Remove an outdated test output file

It was accidentally introduced during some rebase, but it's no longer necessary and `--bless` removes it, but it doesn't fail testing.

Rollup merge of #65410 - Centril:intersection-pat-recover, r=davidtwco,varkor 
syntax: add parser recovery for intersection- / and-patterns `p1 @ p2`

Fixes https://github.com/rust-lang/rust/issues/65400.

The recovery comes in two flavors:

1. We know that `p2` is a binding so we can invert as `p2 @ p1`:

```rust
error: pattern on wrong side of `@`
  --> $DIR/intersection-patterns.rs:13:9
   |
LL |         Some(x) @ y => {}
   |         -------^^^-
   |         |         |
   |         |         binding on the right, should be to the left
   |         pattern on the left, should be to the right
   |         help: switch the order: `y @ Some(x)`
```

2. Otherwise we emit a generic diagnostic for the lack of support for intersection patterns:

```rust
error: left-hand side of `@` must be a binding
  --> $DIR/intersection-patterns.rs:23:9
   |
LL |         Some(x) @ Some(y) => {}
   |         -------^^^-------
   |         |         |
   |         |         also a pattern
   |         interpreted as a pattern, not a binding
   |
   = note: bindings are `x`, `mut x`, `ref x`, and `ref mut x`
```

For more on and-patterns, see e.g. https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/pattern-matching#and-pattern.

Rollup merge of #65340 - bjorn3:cg_ssa_refactor4, r=eddyb 
Several changes to the codegen backend organization

* Split functions from values in cg_ssa `BackendTypes`.
* Remove `is_const_integral` function from `ConstMethods`.
* Actually register the invalid monomorphization of intrinsic long diagnostic and remove the `diagnostics` method from `CodegenBackends`, as it was unused.
* Add cg_ssa and cg_utils provided methods to `default_provide`, so codegen backend don't have to do it themself.

Rollup merge of #65332 - RalfJung:fmt, r=cramertj 
std::fmt: reorder docs

This moves the "Formatting Parameters" section up above right after the discussion of named and positional arguments. Then comes the "Syntax" section, summarizing the discussion of format string syntax.
And only *then* we get to "Formatting Traits" -- that section has some *huge* code examples, so it really should not interrupt the discussion of the grammar. Also users are much more likely to come here to learn about the format string grammar than to come here to learn about the `Binary` trait.
