Add union justifications to conflicting borrows. This commit adds justifications to error messages for conflicting borrows of union fields. Where previously an error message would say ``cannot borrow `u.b` as mutable..``, it now says ``cannot borrow `u` (via `u.b`) as mutable..``. 2018-12-24 13:22:25 -06:00			error[E0502]: cannot borrow `u` (via `u.z.c`) as immutable because it is also borrowed as mutable (via `u.s.a`)
Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed. 2021-04-03 06:05:11 -05:00			`--> $DIR/issue-45157.rs:27:20`

Clearer later use messages for calls Give a special message when the later use is from a call. Use the span of the callee instead of the whole expression. For conflicting borrow messages say that the later use is of the first borrow. 2018-09-29 05:47:47 -05:00			`\| ---- mutable borrow later used here`
