10853f71f2 Auto merge of #8694 - Jarcho:check_proc_macro, r=xFrednet
More proc-macro detection

fixes #6514
fixes #8683
fixes #6858
fixes #6594

This is a more general way of checking if an expression comes from a macro and could be trivially applied to other lints. Ideally this would be fixed in rustc's proc-macro api, but I don't see that happening any time soon.

changelog: FPs: [`unit_arg`] [`default_trait_access`] [`missing_docs_in_private_items`]: No longer trigger in code generated from proc-macros.

09f9acea0a Shrink Token.
From 72 bytes to 12 bytes (on x86-64).

There are two parts to this:
- Changing various source code offsets from 64-bit to 32-bit. This is
  not a problem because the rest of rustc also uses 32-bit source code
  offsets. This means `Token` is no longer `Copy` but this causes no
  problems.
- Removing the `RawStrError` from `LiteralKind`. Raw string literal
  invalidity is now indicated by a `None` value within
  `RawStr`/`RawByteStr`, and the new `validate_raw_str` function can be
  used to re-lex an invalid raw string literal to get the `RawStrError`.

There is one very small change in behaviour. Previously, if a raw string
literal matched both the `InvalidStarter` and `TooManyHashes` cases,
the latter would override the former. This has now changed, because
`raw_double_quoted_string` now uses `?` and so returns immediately upon
detecting the `InvalidStarter` case. I think this is a slight
improvement to report the earlier-detected error, and it explains the
change in the `test_too_many_hashes` test.

The commit also removes a couple of comments that refer to #77629 and
say that the size of these types don't affect performance. These
comments are wrong, though the performance effect is small.

Lint `[single_match]` on `Option` matches

changelog: did some cleanup of the logic for ``[`single_match`]`` and ``[`single_match_else`]`` which fixes the bug where `Option` matches were not linted unless a wildcard was used for one of the arms.
