    refactor(ast_tools): move limit for inlining to a const in `Visit` generator (#10291)

    Pure refactor. `Visit` generator adds `#[inline]` attr to visitor methods containing 5 or less statements. Make this limit a `const`, rather than having it inline in multiple places.

    refactor(ast_tools): make visit call generator functions generic (#10290)

    Pure refactor. Make functions in `Visit` generator which generate `visitor.visit_*(...)` statements generic over `VisitorOutputs`.

    `VisitorOutputs` trait represents a set of outputs. In generator for `Visit` and `VisitMut`, there are 2 outputs for the 2 traits. But other generators need to be able to just generate `Visit` alone. Preparatory work for #10292.

    refactor(ast_tools): change methods to free functions in `Visit` generator (#10289)

    Pure refactor. Move methods of `VisitBuilder` which generate `visitor.visit_*(...)` statements to be free functions, so that they can be exported and used by other generators. Preparatory work for #10292.

    perf(transformer/jsx): speed up decoding `JSXText` strings (#9741)

    close: #10249

    Speed up transforming `JSXText` nodes by:

    1. Avoiding allocations (construct strings directly in arena, with no intermediate `String`s).
    2. Where no HTML entity decoding or string concatenation is required, reuse a slice of source text, rather than generating a new `Atom` and copying string data.

    test(transformer/jsx): tests for `JSXText` strings (#10324)

    Add tests for transforming `JSXText` and `JSXAttributeValue`. Tests cover:

    * Whitespace and line breaks.
    * HTML entities ([`HTMLCharacterReference`](https://facebook.github.io/jsx/#sec-HTMLCharacterReference)).

    fix(ast): Handle `TSThisType` in `TSTypePredicate` (#10328)

    Part of #9705

    When given this code:

    ```ts
    interface X {
      y(): this is { z: 1 }
    }
    ```

    Currently the parser treats `this` inside the type annotation as
    `Identifier` named `this`, but it should be `TSThisType`.

    fix(transformer/react): correct comment (#10323)

    Fix comment in function for decoding HTML entities in `JSXText` elements. Hex code escape is `&#x1234;` not `&x1234;`.

    Also reformat comments in this function.

    refactor(ast/estree): simplify serialization for `JSXOpeningFragment` (#10316)

    Follow-on after #10208.

    We can remove the `JSXOpeningFragmentAttributes` serializer, and use `TsEmptyArray` instead.

    This results in `attributes?: []` in the TS type def, which seems reasonable since a JSX fragment can't have attributes. Really this field shouldn't exist at all! It can probably be considered a mistake in `acorn-jsx` that it does.

    fix(ast/estree): Fix `JSXOpeningFragment` (#10208)

    Fix `JSXOpeningFragment` node estree TS serialization by skipping
    `selfClosing` and `attributes` fields when AST is TS.

    Part of our broader work to align our AST's ESTree output with that of
    TS-ESLint's. Relates to #9705

    fix(ast/estree): fix span for `TemplateElement` in TS AST (#10315)

    Part of #9705.

    TS-ESLint differs from Acorn in the `span` of `TemplateElement`.

    TS-ESLint includes the preceding `` ` `` or `}` and following `${` or `` ` `` in the span.

    ```js
    const template = `abc${x}def${x}ghi`;
    // Acorn:         ^^^    ^^^    ^^^
    // TS-ESLint:    ^^^^^^ ^^^^^^ ^^^^^
    ```

    Make the span follow TS-ESLint in the TS AST.

    refactor(linter): update comments, improve tests, add variant All to LintFilterKind (#10259)

    I split this PR into easily reviewable commits. While working on this
    PR, I noticed two possible follow up changes:

    `LintFilterKind::Rule` and `LintFilterKind::Generic` behave exactly the
    same in `ConfigStoreBuilder::with_filter` because `LintFilterKind::Rule`
    never actually uses or checks for the plugin it stores. Should I include
    the check for plugin?

    The proposed fifth `LintFilterKind` isn't implemented yet (see: `//
    TODO: plugin + category? e.g -A react:correctness)`). Should I add it?

    fix(linter): nested configuration directory resolution (#10157)

    Fixes #10156

    I'm not very familiar with the inner workings of this project - this was
    a fix based on what I could understand after exploring the codebase for
    the first time. @camchenry It would be great to get your eyes on this
    since you are familiar with the nested config implementation.
