Auto merge of #104688 - flip1995:clippyup, r=Manishearth,flip1995
Update Clippy

r? `@Manishearth`

Sorry for taking so long. There were so many blockers and so little time. This situation should be mitigated with #104007 in the future.

-### What it does
-Checks for items annotated with `#[inline(always)]`,
-unless the annotated function is empty or simply panics.
-
-### Why is this bad?
-While there are valid uses of this annotation (and once
-you know when to use it, by all means `allow` this lint), it's a common
-newbie-mistake to pepper one's code with it.
-
-As a rule of thumb, before slapping `#[inline(always)]` on a function,
-measure if that additional function call really affects your runtime profile
-sufficiently to make up for the increase in compile time.
-
-### Known problems
-False positives, big time. This lint is meant to be
-deactivated by everyone doing serious performance work. This means having
-done the measurement.
-
-### Example
-```
-#[inline(always)]
-fn not_quite_hot_code(..) { ... }
-```
