dcc6c28c53 Introduce a ConstPropMachine 
This allows us to avoid changing things directly in the miri engine just
for const prop.

fadfd92c2f Don't run the ConstProp MIR pass on generators 
This can cause cycles as `ConstProp` uses `layout_of` which, for
generators, uses `optimized_mir` which runs `ConstProp`.

Rollup merge of #60928 - TheSirC:fix/60229, r=eddyb 
Changes the type `mir::Mir` into `mir::Body`

Fixes part 1 of #60229 (previously attempted in #60242).

I stumbled upon the issue and it seems that the previous attempt at solving it was not merged. This is a second try more up-to-date.

The commit should have changed comments as well.
At the time of writting, it passes the tidy and check tool.

46b9ed4fa1 Rename "Associated*" to "Assoc*" 
We are going to uniform the terminology of all associated items.
Methods that may or may not have `self` are called "associated
functions". Because `AssociatedFn` is a bit long, we rename `Associated`
to `Assoc`.

Cleanup the MIR visitor

* Remove useless `BasicBlock` parameters on methods with `Location`s.
* Prefer `visit_terminator_kind` to `visit_terminator`.
* Remove `Region` from PlaceContexts. `visit_rvalue` should be used when the region is important.
* Remove unused visitor methods.

Rollup merge of #59514 - tmandry:remove-adt-def-from-projection-elem, r=eddyb 
Remove adt_def from projections and downcasts in MIR

As part of optimizing generator layouts in MIR, we'd like to allow downcasting generators to variants which do not have a corresponding `def_id`, since they are created by the compiler.

This refactor hopes to allow that, without regressing perf.
