gccrs: parser: Parse reference patterns correctly
Reference patterns cannot contain AltPatterns per the Rust reference,
so we should not call into `parse_pattern` to parse the referenced pattern,
but rather the more restrictive `parse_pattern_no_alt`.
gcc/rust/ChangeLog:
* parse/rust-parse-impl.h (Parser::parse_reference_pattern): Do not
call into `parse_pattern` anymore.
gcc/testsuite/ChangeLog:
* rust/compile/issue-1807.rs: New test.
