21a870515b Fix clippy::needless_borrow in the compiler 
`x clippy compiler -Aclippy::all -Wclippy::needless_borrow --fix`.

Then I had to remove a few unnecessary parens and muts that were exposed
now.

73100d8e93 Rollup merge of #117317 - RalfJung:track-caller, r=oli-obk 
share some track_caller logic between interpret and codegen

Also move the code that implements the track_caller intrinsics out of the core interpreter engine -- it's just a helper creating a const-allocation, doesn't need to be part of the interpreter core.

0fd7ce99b0 Auto merge of #116010 - RalfJung:more-typed-immediates, r=oli-obk 
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. :)

`LayoutError` is 24 bytes, which is bigger than the `Ok` types, so let's
shrink that.

9e5573a0d2 Use 128 bits for TypeId hash 
- Switch TypeId to 128 bits
- Hack around the fact that tracing-subscriber dislikes how TypeId is hashed
- Remove lowering of type_id128 from rustc_codegen_llvm
- Remove unnecessary `type_id128` intrinsic (just change return type of `type_id`)
- Only hash the lower 64 bits of the TypeId
- Reword comment

5460f92a0f Rollup merge of #112168 - scottmcm:lower-div-rem-unchecked-to-mir, r=oli-obk 
Lower `unchecked_div`/`_rem` to MIR's `BinOp::Div`/`Rem`

As described in <https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/enum.BinOp.html#variant.Div>, the ordinary `BinOp`s for these are already UB for division by zero ([or overflow](https://llvm.org/docs/LangRef.html#sdiv-instruction), [demo](https://rust.godbolt.org/z/71e7P7Exh)), as MIR building is responsible for inserting code to panic for those cases regardless of whether the overflow checks are enabled.

So we can lower these in the same arm that lowers `wrapping_add` to MIR `BinOp::Add` and such, as all these cases turn into ordinary `Rvalue::BinaryOp`s.

05a665f21a Lower intrinsics::offset to mir::BinOp::Offset 
They're semantically the same, so this means the backends don't need to handle the intrinsic and means fewer MIR basic blocks in pointer arithmetic code.

64cce5fc7d Add CastKind::Transmute to MIR 
Updates `interpret`, `codegen_ssa`, and `codegen_cranelift` to consume the new cast instead of the intrinsic.

Includes `CastTransmute` for custom MIR building, to be able to test the extra UB.

6ce78a31d8 Rollup merge of #108669 - Nilstrieb:query-my-uninitness, r=compiler-errors 
Allow checking whether a type allows being uninitialized

This is useful for clippy ([rust-lang/clippy#10407](https://github.com/rust-lang/rust-clippy/issues/10407)) and for the future `MaybeUninit::assume_init` panics (#100423).
