[sophiajt]

From: src/test/compile-fail/E0435.rs

E0435 needs a span_label, updating it from:

error[E0435]: attempt to use a non-constant value in a constant
  --> src/test/compile-fail/E0435.rs:13:23
   |
13 |     const FOO : u32 = foo; //~ ERROR E0435
   |                       ^^^

To:

error[E0435]: attempt to use a non-constant value in a constant
  --> src/test/compile-fail/E0435.rs:13:23
   |
13 |     const FOO : u32 = foo; //~ ERROR E0435
   |                       ^^^ non-constant used with constant
