Rollup merge of #67536 - Centril:move-is_range_literal, r=Mark-Simulacrum 
Move `{hir::lowering -> hir}::is_range_literal`

The function is never used inside lowering, but only ever in external crates.
By moving it, we facilitate lowering as its own crate.

Best read commit-by-commit.

Rollup merge of #67527 - GuillaumeGomez:results-show-too-much, r=kinnison 
Results show too much

Fixes #67461.

To reproduce the current issue: search anything, then once the results appears, press escape. They should disappear then re-appear right away. This is because blurring an element triggers the "change" event.

Rollup merge of #67507 - Mark-Simulacrum:purge-uninit, r=Centril 
Remove mem::uninitalized from tests

This purges uses of uninitialized where possible from test cases. Some
are merely moved over to the equally bad pattern of
MaybeUninit::uninit().assume_init() but with an annotation that this is
"the best we can do".

Fixes #62397

a916ac22b9 Auto merge of #67540 - Mark-Simulacrum:fmt-the-world, r=Centril 
Format the world

This PR modifies the formatting infrastructure a bit in the first commit (to enable the forgotten 2018 edition), as well as removes most directories from the ignore list in rustfmt.toml. It then follows that up with the second commit which runs `x.py fmt` and formats the entire repository.

We continue to not format the test directory (`src/test`) because of interactions with pretty printing and, in part, because re-blessing all of those files is somewhat harder to review, so is best suited for a follow up PR in my opinion.

0f24ccd21d Change bound order in rustfmt test 
It is unclear why this changed, but since it seems like a harmless
change, we're going to move forward with reformatting.
