A test case was also created for this situation to prevent the problem occuring again. A similar problem was also fixed for the symbol method. There was some minor code cleanup.

New macro utils changelog: none Sorry, this is a big one. A lot of interrelated changes and I wanted to put the new utils to use to make sure they are somewhat battle-tested. We may want to divide some of the lint-specific refactoring commits into batches for smaller reviewing tasks. I could also split into more PRs. Introduces a bunch of new utils at `clippy_utils::macros::...`. Please read through the docs and give any feedback! I'm happy to introduce `MacroCall` and various functions to retrieve an instance. It feels like the missing puzzle piece. I'm also introducing `ExpnId` from rustc as "useful for Clippy too". `@rust-lang/clippy` Fixes rust-lang#7843 by not parsing every node of macro implementations, at least the major offenders. I probably want to get rid of `is_expn_of` at some point.
