E0055 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0055.rs

Error E0055 needs a span_label, updating it from:

error[E0055]: reached the recursion limit while auto-dereferencing Foo
  --> src/test/compile-fail/E0055.rs:21:13
   |
21 |     ref_foo.foo(); //~ ERROR E0055
   |             ^^^

To:

error[E0055]: reached the recursion limit while auto-dereferencing Foo
  --> src/test/compile-fail/E0055.rs:21:13
   |
21 |     ref_foo.foo(); //~ ERROR E0055
   |             ^^^ deref recursion limit reached

Bonus: there may be a better wording for the label. Suggestions welcome!
