Except for `simd-intrinsic/`, which has a lot of files containing
multiple types like `u8x64` which really are better when hand-formatted.
There is a surprising amount of two-space indenting in this directory.
Non-trivial changes:
- `rustfmt::skip` needed in `debug-column.rs` to preserve meaning of the
test.
- `rustfmt::skip` used in a few places where hand-formatting read more
nicely: `enum/enum-match.rs`
- Line number adjustments needed for the expected output of
`debug-column.rs` and `coroutine-debug.rs`.

Previously, it was only put on scalars with range validity invariants
like bool, was uninit was obviously invalid for those.
Since then, we have normatively declared all uninit primitives to be
undefined behavior and can therefore put `noundef` on them.
The remaining concern was the `mem::uninitialized` function, which cause
quite a lot of UB in the older parts of the ecosystem. This function now
doesn't return uninit values anymore, making users of it safe from this
change.
The only real sources of UB where people could encounter uninit
primitives are `MaybeUninit::uninit().assume_init()`, which has always
be clear in the docs about being UB and from heap allocations (like
reading from the spare capacity of a vec. This is hopefully rare enough
to not break anything.
