Get all (but one) of debuginfo tests to pass with MIR codegen.
I didn't get much feedback in #31005 so I went ahead and implemented something simple.
Closes#31005, as MIR debuginfo should work now for most usecases.
The `no-debug-attribute` test no longer assumes variables are in scope of `return`.
We might also want to revisit that in #32949, but the test is more reliable now either way.
In order to get one last function in the `associated-type` test pass, this PR also fixes#32790.
Implement `pub(restricted)` privacy (RFC 1422)
This implements `pub(restricted)` privacy from RFC 1422 (cc #32409) behind a feature gate.
`pub(restricted)` paths currently cannot use re-exported modules both for simplicity of implementation and for future compatibility with RFC 1560 (cf #31783).

Add initial version of codegen unit partitioning for incremental compilation.
The task of the partitioning module is to take the complete set of translation items of a crate and produce a set of codegen units from it, where a codegen unit is a named set of (translation-item, linkage) pairs. That is, this module decides which translation item appears in which codegen units with which linkage.
This version only handles the case of partitioning for incremental compilation, not the regular N-codegen units case. In the future the regular case should be handled too, maybe even doing a bit more analysis to intelligently figure out a good partitioning.
One thing that could be improved is the syntax of the codegen unit tests. Right now they still use the compile-fail error specification infrastructure, so everything has to be on one line. Would be nice to be able to format things in a more readable way.
Deduplicate libraries on hash instead of filename.
Removes the need for canonicalization to prevent #12459.
(Now with passing tests!)
Canonicalization breaks certain environments where the libraries are symlinks to files that don't end in .rlib (e.g. /remote/cas/$HASH).
Replace consider_unification_despite_ambiguity with new obligation variant
Is work towards #32730. Addresses part one of #32286. Addresses #24210 and #26046 to some degree.

Handle operand temps for function calls
Previously, all non-void function returns required an on-stack location for the value to be stored to. This code improves translation of function calls so this is no longer necessary.
Save/load incremental compilation dep graph
Contains the code to serialize/deserialize the dep graph to disk between executions. We also hash the item contents and compare to the new hashes. Also includes a unit test harness. There are definitely some known limitations, such as https://github.com/rust-lang/rust/issues/32014 and https://github.com/rust-lang/rust/issues/32015, but I am leaving those for follow-up work.
Note that this PR builds on https://github.com/rust-lang/rust/pull/32007, so the overlapping commits can be excluded from review.

Reinstate fast_reject for overlap checking
The initial implementation of specialization did not use the
`fast_reject` mechanism when checking for overlap, which caused a
serious performance regression in some cases.
This commit modifies the specialization graph to use simplified types
for fast rejection when possible, and along the way refactors the logic
for building the specialization graph.
Closes#32499

Lay groundwork for RFC 1422 and improve `PrivateItemsInPublicInterfacesVisitor`
This PR lays groundwork for RFC 1422 (cc #32409) and improves `PrivateItemsInPublicInterfacesVisitor`. More specifically, it
- Refactors away `hir::Visibility::inherit_from`, the semantics of which are obsolete.
- Makes `hir::Visibility` non-`Copy` so that we will be able to add new variants to represent `pub(restricted)` (for example, `Visibility::Restricted(Path)`).
- Adds a new `Copy` type `ty::Visibility` that represents a visibility value, i.e. a characterization of where an item is accessible. This is able to represent `pub(restricted)` visibilities.
- Improves `PrivateItemsInPublicInterfacesVisitor` so that it checks for items in an interface that are less visible than the interface. This fixes#30079 but doesn't change any other behavior.

Suggest adding a where-clause when that can help

You can now pass `-Z incremental=dir` as well as saying `-Z
query-dep-graph` if you want to enable queries for some other
purpose. Accessor functions take the place of computed boolean flags.
