auto merge of #12370 : rcxdude/rust/macro_fix, r=alexcrichton
Closes #11692. Instead of returning the original expression, a dummy expression (with identical span) is returned. This prevents infinite loops of failed expansions as well as odd double error messages in certain situations. This is a slightly better fix than #12197, because it does not produce a double error and also fixes a few other cases where an infinite loop could happen. This does not fix the other issue in #11692 (non-builtin macros not being recognised when expanded inside macros), which I think should be moved into a separate issue.
