Make non-ASCII errors more consistent. There are three kinds of "byte" literals: byte literals, byte string literals, and raw byte string literals. None are allowed to have non-ASCII chars in them. Two `EscapeError` variants exist for when that constraint is violated. - `NonAsciiCharInByte`: used for byte literals and byte string literals. - `NonAsciiCharInByteString`: used for raw byte string literals. As a result, the messages for raw byte string literals use different wording, without good reason. Also, byte string literals are incorrectly described as "byte constants" in some error messages. This commit eliminates `NonAsciiCharInByteString` so the three cases are handled similarly, and described correctly. The `mode` is enough to distinguish them. Note: Some existing error messages mention "byte constants" and some mention "byte literals". I went with the latter here, because it's a more correct name, as used by the Reference. 2022-11-03 15:17:37 +11:00			`#[rustc_dummy = b"ﬃ.rs"] //~ ERROR non-ASCII character in byte string literal`
