Error message all end up passing into a function as an `impl
Into<{D,Subd}iagnosticMessage>`. If an error message is creatd as
`&format("...")` that means we allocate a string (in the `format!`
call), then take a reference, and then clone (allocating again) the
reference to produce the `{D,Subd}iagnosticMessage`, which is silly.
This commit removes the leading `&` from a lot of these cases. This
means the original `String` is moved into the
`{D,Subd}iagnosticMessage`, avoiding the double allocations. This
requires changing some function argument types from `&str` to `String`
(when all arguments are `String`) or `impl
Into<{D,Subd}iagnosticMessage>` (when some arguments are `String` and
some are `&str`).

I'm not sure this is a good idea as this error code is to be migrated away from, and some crates have migration PRs open for a while already, and this PR might cause conflicts for them. Edit: talking about the second commit. The first commit is fine. |

There was a problem hiding this comment.
A couple .as_str()s that I don't really understand, but otherwise LGTM.
