Auto merge of #29215 - fhahn:issue-28157-bad-semicolon, r=alexcrichton

Browse source 
PR for #28157. At the moment, `rustc` emits a warning when a bare semicolon is encountered (could also be a fail, but I think this is a backwards incompatible change).

Also I am not sure where the best place for a test for that warning would be. Seems run-pass tests do not check warnings.
