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 usages of `Iterator::flat_map()` where `filter_map()` could be
-used instead.
-
-### Why is this bad?
-When applicable, `filter_map()` is more clear since it shows that
-`Option` is used to produce 0 or 1 items.
-
-### Example
-```
-let nums: Vec<i32> = ["1", "2", "whee!"].iter().flat_map(|x| x.parse().ok()).collect();
-```
-Use instead:
-```
-let nums: Vec<i32> = ["1", "2", "whee!"].iter().filter_map(|x| x.parse().ok()).collect();
-```
