3482: Fix regression from #3451 r=matklad a=edwin0cheng There is a regression from #3451 such that the following code has failed to parse in raw item collecting phase: ```rust macro_rules! with_std { ($($i:item)*) => ($(#[cfg(feature = "std")]$i)*) } with_std! { mod macros; mod others; } ``` ### Rationale We always assume the last token of an statement will not end with a whitespace, which is true. It is because in parsing phase, we always emit `SyntaxNode` before any whitespace. Such that in various parts of RA code, we solely check the semi-colon by using `SyntaxNode::last_child_token() == ";"` . However, in #3451, we insert some whitespaces between puncts such that we broke above assumption. This PR fixed this bug by make sure we don't add any whitespace if it is a semicolon.
