Some places use the local `tcx` variable, some use `self.tcx()`. This commit removes the local variable so that all places use `self.tcx()`, for consistency.
This wins 6% on `unicode_normalization`, by avoiding a call to `lub_concrete_regions()` and a `Region` equality test.
The function only has one call site, so we don't need a tag argument.
The associated long diagnostic didn't get registered before
It means an allocation is required to create an empty `TokenStream`, but all other operations are simpler and marginally faster due to not having to check for `None`. Overall it simplifies the code for a negligible performance effect. The commit also removes `TokenStream::empty` by implementing `Default`, which is now possible.
This avoids some unnecessary creation of empty token streams.
Use a more traditional scheme with providing them as a resolver output

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.
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.

Bring attention to suggestions when the only difference is capitalization CC rust-lang#65386.
…=davidtwco,varkor syntax: add parser recovery for intersection- / and-patterns `p1 @ p2` Fixes rust-lang#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. r? @davidtwco cc @varkor @lzutao
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.
