This change ensures that a function signature always starts with an `IdentifierNameMaybeBeforeSignature` node (renamed from `IdentifierNameBeforeParams`), even in the case of function declarations like `fn F -> T` that have no parameter list. As a consequence, this ensures that we push new entries onto `pattern_block_stack` and `full_pattern_stack` when we start processing the function signature.
