Error E0107 needs a span_label, updating it from:

error[E0107]: wrong number of lifetime parameters: expected 1, found 0
  --> src/test/compile-fail/E0107.rs:20:10
   |
20 |     foo: Foo, //~ ERROR E0107
   |          ^^^

error[E0107]: wrong number of lifetime parameters: expected 0, found 1
  --> src/test/compile-fail/E0107.rs:21:10
   |
21 |     bar: Bar<'a>, //~ ERROR E0107
   |          ^^^^^^^

To:

error[E0107]: wrong number of lifetime parameters: expected 1, found 0
  --> src/test/compile-fail/E0107.rs:20:10
   |
20 |     foo: Foo, //~ ERROR E0107
   |          ^^^ expected 1 lifetime parameter

error[E0107]: wrong number of lifetime parameters: expected 0, found 1
  --> src/test/compile-fail/E0107.rs:21:10
   |
21 |     bar: Bar<'a>, //~ ERROR E0107
   |          ^^^^^^^ unexpected lifetime parameter

This assumes we can see how many lifetime parameters we expect, and update the label accordingly.
