Disallow comments in try-catch-finally at unexpected locations

[paul-dingemans]

Description

Disallow comments in try-catch-finally at unexpected locations. Merging a catch/finally block with closing curly brace at previous line, will no longer result in compilation error if that curly brace was followed by an EOL comment.

Closes #2427
