150d1fee04 Auto merge of #79322 - jyn514:refactor-impl, r=estebank 
Separate out a `hir::Impl` struct

This makes it possible to pass the `Impl` directly to functions, instead
of having to pass each of the many fields one at a time. It also
simplifies matches in many cases.

See `rustc_save_analysis::dump_visitor::process_impl` or `rustdoc::clean::clean_impl` for a good example of how this makes `impl`s easier to work with.

r? `@petrochenkov` maybe?

2e92b13a60 Prevent caching projections in the case of cycles 
When normalizing a projection which results in a cycle, we would
cache the result of `project_type` without the nested obligations
(because they're not needed for inference). This would result in
the nested obligations only being handled once in fulfill, which
would avoid the cycle error.

Fixes #79714, a regresion from #79305 caused by the removal of
`get_paranoid_cache_value_obligation`.

0c11b93f5a Auto merge of #79635 - lcnr:const-eval-idk, r=oli-obk 
const_evaluatable_checked: fix occurs check

fixes #79615

this is kind of a hack because we use `TypeRelation` for both the `Generalizer` and the `ConstInferUnifier` but i am not sure if there is a useful way to disentangle this without unnecessarily duplicating some code.

The error in the added test is kind of unavoidable until we erase the unused substs of `ConstKind::Unevaluated`. We talked a bit about this in the cg lazy norm meeting (https://rust-lang.zulipchat.com/#narrow/stream/260443-project-const-generics/topic/lazy_normalization_consts)
