E0195 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0195.rs

Error E0195 needs a span_label, updating it from:

error[E0195]: lifetime parameters or bounds on method `bar` do not match the trait declaration
  --> src/test/compile-fail/E0195.rs:18:5
   |
18 |     fn bar<'a,'b>(x: &'a str, y: &'b str) { //~ ERROR E0195
   |     ^

To:

error[E0195]: lifetime parameters or bounds on method `bar` do not match the trait declaration
  --> src/test/compile-fail/E0195.rs:18:5
   |
18 |     fn bar<'a,'b>(x: &'a str, y: &'b str) { //~ ERROR E0195
   |     ^ lifetimes do not match trait

Bonus: Underline the lifetimes and show the original trait requirement:

error[E0195]: lifetime parameters or bounds on method `bar` do not match the trait declaration
  --> src/test/compile-fail/E0195.rs:18:5
   |
13 |     fn bar<'a,'b:'a>(x: &'a str, y: &'b str);
   |           ---------- original trait requirement
...
18 |     fn bar<'a,'b>(x: &'a str, y: &'b str) { //~ ERROR E0195
   |           ^^^^^^^ lifetimes do not match trait

I'd like to work on it.
