adjust how closure/generator types are printed
I saw `&[closure@$DIR/issue-20862.rs:2:5]` and I thought it is a slice type, because that's usually what `&[_]` is... it took me a while to realize that this is just a confusing printer and actually there's no slice. Let's use something that cannot be mistaken for a regular type.

If we also land https://github.com/rust-lang/rust/pull/115020 , the 2nd backtrace disappears, hopefully making the "panic in a destructor during cleanup" easier to see.

Get `!nonnull` metadata on slice iterators, without `assume`s
This updates the non-ZST paths to read the end pointer through a pointer-to-`NonNull`, so that they all get `!nonnull` metadata.
That means that the last `assume(!ptr.is_null())` can be deleted, without impacting codegen -- the codegen tests confirm the LLVM-IR ends up exactly the same as before.

It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related

are only coercion to make it clear why only some pointer related "casts" are in the enum.

...
There's no need for the `const_eval_select` dance here. And while I originally wrote the `.try_into().unwrap_unchecked()` implementation here, it's kinda a mess in MIR -- this new one is substantially simpler, as shown by the old one being above the inlining threshold but the new one being below it.
