Remove unncessary check for macro call
Since `macro_rules` is a contextual keyword, it is an `IDENT` token and thus `is_path_start` already identifies it correctly. You can tell the previous check is unnecessary because the relevant tests still pass.
internal: Improve readability of the parser code
The code is basically equivalent to the previous version, but it improves the readability by making it much more simpler and concise.
fix: Don't invalid body query results when generating desugared names
The hack remains until we get hygiene, but with this the generated names are stable across bodies
fix: Remove accidental dependency between `parse_macro_expansion` and `parse`
Turns out my idea from https://github.com/rust-lang/rust-analyzer/pull/15251 causes all builtin derive expansions to obviously rely on the main parse, meaning the entire `macro_arg` layer becomes kind of pointless. So this reverts that PR again.
internal: Implement parent-child relation for `SourceRoot`s
This commit adds the said relation by keeping a map of type `FxHashMap<SourceRootId,Option<SourceRootId>>` inside the `GlobalState`. Its primary use case is reading `rust-analyzer.toml`(#13529) files that can be placed in every local source root. As a config will be found by traversing this "tree" we need the parent information for every local source root. This commit omits defining this relation for library source roots entirely.

fix: panic when using float numbers without dots in chain calls
Fix#16278.
This PR fixes the panic caused by using floating-point numbers without a dot (such as `1e2`) in chain calls.
-------------
Although this syntax is very odd 🤣, r-a should not panic.
fix: keep attributes in assist 'generate_delegate_trait'
fix#15198.
This PR address the issue that `impl` generated by `generate_delegate_trait` doesn't keep attributes.
