Rollup merge of #54415 - petrochenkov:norollback, r=estebank
parser: Tweak function parameter parsing to avoid rollback on succesfull path Since rollback is not perfect and may e.g. leave non-fatal errors after it, we need to make sure compilation fails if it happens. So in particular case of `fn parse_arg_general` we need to parse the "good" `TYPE` first and only then rollback and recover erroneous `PAT: TYPE` if necessary. Found when working on https://github.com/rust-lang/rfcs/pull/2544#issuecomment-423293222. r? @ghost
