Rollup merge of #135748 - compiler-errors:len-2, r=RalfJung,oli-obk
Lower index bounds checking to `PtrMetadata`, this time with the right fake borrow semantics 😸 Change `Rvalue::RawRef` to take a `RawRefKind` instead of just a `Mutability`. Then introduce `RawRefKind::FakeForPtrMetadata` and use that for lowering index bounds checking to a `PtrMetadata`. This new `RawRefKind::FakeForPtrMetadata` acts like a shallow fake borrow in borrowck, which mimics the semantics of the old `Rvalue::Len` operation we're replacing. We can then use this `RawRefKind` instead of using a span desugaring hack in CTFE. cc ``@scottmcm`` ``@RalfJung``
