b1430fb7ca Fix a bunch of typo
This PR will fix some typos detected by [typos].

I only picked the ones I was sure were spelling errors to fix, mostly in
the comments.

Rollup merge of #101101 - RalfJung:read-pointer-as-bytes, r=oli-obk
interpret: make read-pointer-as-bytes a CTFE-only error with extra information

Next step in the reaction to https://github.com/rust-lang/rust/issues/99923. Also teaches Miri to implicitly strip provenance in more situations when transmuting pointers to integers, which fixes https://github.com/rust-lang/miri/issues/2456.

Pointer-to-int transmutation during CTFE now produces a message like this:
```
   = help: this code performed an operation that depends on the underlying bytes representing a pointer
   = help: the absolute address of a pointer is not known at compile-time, so such operations are not supported
```

a7468c60f8 Auto merge of #99472 - RalfJung:provenance, r=oli-obk
interpret: rename Tag/PointerTag to Prov/Provenance

We were pretty inconsistent with calling this the "tag" vs the "provenance" of the pointer; I think we should consistently call it "provenance".

0ec3269db8 interpret: rename Tag/PointerTag to Prov/Provenance
Let's avoid using two different terms for the same thing -- let's just call it "provenance" everywhere.
In Miri, provenance consists of an AllocId and an SbTag (Stacked Borrows tag), which made this even more confusing.

Rollup merge of #99259 - RalfJung:visit-a-place, r=oli-obk
interpret/visitor: support visiting with a PlaceTy

Finally we can visit a `PlaceTy` in a way that will only do `force_allocation` when needed ti visit a field. :)

ab225ade1e interpret: refactor projection handling code
Moves our projection handling code into a common file, and avoids the use of a
general mplace-based fallback function by have more specialized implementations.

mplace_index (and the other slice-related functions) could be more efficient by
copy-pasting the body of operand_index. Or we could do some trait magic to share
the code between them. But for now this is probably fine.
