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 usage of unconstrained numeric literals which may cause default numeric fallback in type
-inference.
-
-Default numeric fallback means that if numeric types have not yet been bound to concrete
-types at the end of type inference, then integer type is bound to `i32`, and similarly
-floating type is bound to `f64`.
-
-See [RFC0212](https://github.com/rust-lang/rfcs/blob/master/text/0212-restore-int-fallback.md) for more information about the fallback.
-
-### Why is this bad?
-For those who are very careful about types, default numeric fallback
-can be a pitfall that cause unexpected runtime behavior.
-
-### Known problems
-This lint can only be allowed at the function level or above.
-
-### Example
-```
-let i = 10;
-let f = 1.23;
-```
-
-Use instead:
-```
-let i = 10i32;
-let f = 1.23f64;
-```
