Lots of unnecessary `pub`s in this crate. Most are downgraded to
`pub(super)`, though some don't need any visibility.

When running tests without the `--force-rerun` flag, compiletest will
automatically skip any tests that (in its judgement) don't need to be run again
since the last time they were run.

This patch adds an explicit reason to those skipped tests, which is visible
when running with `rust.verbose-tests = true` in `config.toml`.

Currently it constructs two vectors `calls_to_terminated` and
`cleanups_to_remove` in the main loop, and then processes them after the
main loop. But the processing can be done in the main loop, avoiding the
need for the vectors.

Let chains are perfect for this kind of function.

Nothing comes after it within the loop.

It doesn't need to be, and it's 72 bytes on 64-bit platforms, which is
fairly large.

It's nicer than the `IndexVec` type.

In some cases `target` and `arg` are obtained fallibly, and in some
cases they are obtained infallibly. This commit changes them all to
infallible.

There are four related dataflow structs: `MaybeInitializedPlaces`,
`MaybeUninitializedPlaces`, and `EverInitializedPlaces`,
`DefinitelyInitializedPlaces`. They all have a `&Body` and a
`&MoveData<'tcx>` field. The first three use different lifetimes for the
two fields, but the last one uses the same lifetime for both.

This commit changes the first three to use the same lifetime, removing
the need for one of the lifetimes. Other structs that also lose a
lifetime as a result of this are `LivenessContext`, `LivenessResults`,
`InitializationData`.

It then does similar things in various other structs.

Also put the remaining lifetimes into the usual order.

Give them the names used in most places.

It's a very thin wrapper that pairs `MoveDataBuilder` with a `Location`,
and it has four lifetime arguments. This commit removes it by just
adding a `Location` to `MoveDataBuilder`.

It's a trivial wrapper around `ElaborateDropsCtxt` that serves no
apparent purpose.

Remove redundant check in `symlink_hard_link` test

We support macOS 10.12 and above, so it now always uses `linkat`, and so the check is redundant.

Print a helpful message if any tests were skipped for being up-to-date

When running tests without the `--force-rerun` flag, compiletest will automatically skip any tests that (in its judgement) don't need to be run again since the last time they were run.

This is normally very useful, but can occasionally be confusing, especially in edge-cases where up-to-date checking is not completely accurate (or the test is flaky).

This PR makes bootstrap count the number of tests that were ignored for being up-to-date (via a hard-coded check on the ignore reason), and prints a helpful message when that number is nonzero.

Fix ICE caused by missing span in a region error

Fixes rust-lang#130012

The ICE occurs on line 634 in this error handling code: https://github.com/rust-lang/rust/blob/085744b7ad8b227239bcee0a44cd78dcd0310ab9/compiler/rustc_trait_selection/src/error_reporting/infer/region.rs#L617-L637 It is caused by the span being a dummy span and `!span.is_dummy()` on line 628 evaluating to `false`.

A dummy span, however, is expected here thanks to the `Self: Trait` predicate from `predicates_of` (see line 61): https://github.com/rust-lang/rust/blob/085744b7ad8b227239bcee0a44cd78dcd0310ab9/compiler/rustc_hir_analysis/src/collect/predicates_of.rs#L61-L69

This PR changes the error handling code to omit the note which needed the span instead of ICE'ing in the presence of a dummy span.
