Add a query to get the `promoted`s for a `mir::Body`

This is a builidng block toward removing a lot of duplicated code
between miri and the cosnt-propagator pass.

9007296a20 Add check_mplace_ptr convenience method; provide ptr-normalization methods for mplace and op to avoid repeated int-to-ptr casting during validation. 
Also change Memory::copy to work on `Pointer` instead of `Scalar`.
Also rename some methods from to_* to assert_* that will panic if their precondition is not met.

Fix perf regression from Miri Machine trait changes

Maybe this fixes the perf regression that https://github.com/rust-lang/rust/pull/62003 seemingly introduced?

Rollup merge of #62245 - RalfJung:miri-extra-fn, r=eddyb,zackmdavis 
Miri engine: support extra function (pointer) values

We want to add basic support for `dlsym` in Miri (needed to run the latest version of `getrandom`). For that to work, `dlsym` needs to return *something* that can be stored in a function pointer and later called.

So we add a new `ExtraFnVal` type to the `Machine` trait, and enable Miri's memory to associate allocation IDs with such values, so that `create_fn_alloc` and `get_fn` can work on *both* `Instance` (this is used for "normal" function pointers) and `ExtraFnVal`.

23a1ebb3fc Remove the AllocId from ByRef values 
`ByRef` const values have no identity beyond their value, we should not treat them as having identity. The `AllocId` often differed between equal constants, because of the way that the miri-engine evaluates constants.
