…ram (#7169) Follow-on after stack up to #7148. Small optimization. `ArrowFunctionExpression` is 56 bytes, whereas `ArenaBox<ArrowFunctionExpression>` is 8 bytes. So it's preferable to pass the `ArenaBox<ArrowFunctionExpression>` to `transform_arrow_function_expression` and call `unbox` on it there instead of unboxing *before* passing to the function.

…ne_in` on `LabelIdentifier` (#7172) Follow-on after stack up to #7148. Small optimization. `LabelIdentifier` is `Clone` so we can use `Clone::clone` to clone it, instead of `CloneIn::clone_in`. The difference is that `clone_in` makes a 2nd copy of the `Atom`'s string in the arena, whereas `clone` creates a new `Atom` referencing the same string. This is an unfortunate shortcoming of `CloneIn` (oxc-project/backlog#96), but the more we can avoid `CloneIn`, the better.

… whether within an async generator function (#7170) Follow-on after stack up to #7148. Split `is_inside_async_generator_function` into 2 functions `yield_is_inside_async_generator_function` and `async_is_inside_async_generator_function`. There are a couple of differences between `yield` and `await`, which we can leverage to make both these functions simpler: * `yield` cannot appear at top level (there's no such thing as "top level yield"). * `yield` cannot appear in an arrow function (there's no such thing as a "generator arrow function"). In addition: * Because each function now handles a specific case, no need to check if function containing `async` is an async function. It must be. Ditto for `yield`. * Remove the `if ctx.current_scope_flags().is_top()` check. Probably this check costs more than it saves because top level `await` is far less common than `await` within async functions. So this check was optimizing for an uncommon case, at a cost to the common case. * Add more comments to explain the logic. This is all quite small optimizations, but I was having difficulty understanding the logic, and found that splitting it up made it clearer (at least for me).
