96be3e7cc8 Rollup merge of #122784 - jswrenn:tag_for_variant, r=compiler-errors 
Add `tag_for_variant` query

This query allows for sharing code between `rustc_const_eval` and `rustc_transmutability`. It's a precursor to a PR I'm working on to entirely replace the bespoke layout computations in `rustc_transmutability`.

r? `@compiler-errors`

2de9010f66 Add tag_for_variant query 
This query allows for sharing code between `rustc_const_eval` and
`rustc_transmutability`.

Also moves `DummyMachine` to `rustc_const_eval`.

52f8aec14c Auto merge of #121985 - RalfJung:interpret-return-place, r=oli-obk 
interpret: avoid a long-lived PlaceTy in stack frames

`PlaceTy` uses a representation that's not very stable under changes to the stack. I'd feel better if we didn't have one in the long-term machine state.

interpret: more consistently use ImmTy in operators and casts

The diff in src/tools/miri/src/shims/x86/sse2.rs should hopefully suffice to explain why this is nicer. :)
