5c4b61b4b4
a more general version of https://github.com/rust-lang/rust/pull/146080. after a bit of hacking in [`fluent.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_fluent_macro/src/fluent.rs), i discovered that i'm not the only one that is bad at following guidelines 😅. this pr lowercases the first letter of all the error messages in the codebase. (i did not change things that are traditionally uppercased such as _MIR_, _ABI_ or _C_) i think it's reasonable to run a `@bors try` so all the test suite is checked, as i cannot run some of the tests on my machine. i double checked (and replaced manually) all the old error messages, but better be safe than sorry. in the future i will try to add a check in `x test tidy` that errors if an error message starts with an uppercase letter.
