6908d3ec9e Rollup merge of #120683 - RalfJung:symbolic-alignment-ice, r=oli-obk 
miri: fix ICE with symbolic alignment check on extern static

Fixes https://github.com/rust-lang/miri/issues/3288. Also fixes [this example](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=38ee338ff10726be72bdd6efa3386763).

This could almost be a Miri PR, except for that typo fix in the validator. I started this as a rustc patch since I thought I need rustc changes, and now it'd be too annoying to turn this into a Miri PR...

4abb455529 Update ty::VariantDef to use IndexVec<FieldIdx, FieldDef> 
And while doing the updates for that, also uses `FieldIdx` in `ProjectionKind::Field` and `TypeckResults::field_indices`.

There's more places that could use it (like `rustc_const_eval` and `LayoutS`), but I tried to keep this PR from exploding to *even more* places.

81f3841cfb 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
```
