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.
internal: Remove unused keyword from visibility recovery
We removed support `crate` visibility keyword, but forgot to remove it from the recovery token list.
fix: Preserve $ and \ in postfix format completions
`parse_format_exprs` doesn't escape these two as of #16781, so they have to be escaped as a separate step.
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.
