Rollup merge of #42134 - scottmcm:rangeinclusive-struct, r=aturon
Make RangeInclusive just a two-field struct
Not being an enum improves ergonomics and consistency, especially since NonEmpty variant wasn't prevented from being empty. It can still be iterable without an extra "done" bit by making the range have !(start <= end), which is even possible without changing the Step trait.
This is definitely a breaking change to anything consuming `RangeInclusive` directly (not as an Iterator) or constructing it without using the sugar. Is there some change that would make sense before this so compilation failures could be compatibly fixed ahead of time?

introduce local-scope to prevent `StorageLive`/`StorageDead` in statics
In investigating #36799, I found that we were creating storage-live/storage-dead instructions in statics/constants, where they are not needed. This arose due to the fix for local scopes. This PR tries to fix that (and adds a test -- I'm curious if there is a way to make that test more targeted, though).

remove interior mutability of type-flags
We were previously using the flags on `Ty<'tcx>` instances to do some ad-hoc caching schemes around things like `is_sized()`, `is_freeze()`, and `moves_by_default()`. This PR replaces those schemes with a proper query; the query key is based on the pair of a `(ParameterEnvironment<'tcx>, Ty<'tcx>)` pair. This is also intended to be a preliminary template for what trait-selection and projection will eventually look like.
I did some performance measurements. In the past, I observed a noticeable speedup (6%) for building rustc, but since I've rebased, the numbers appear to be more of a wash:

make ui test output patch compatible #41948
Hello!
Previously with #41474 I've changed the internals of UI test output comparison mechanism.
That change didn't change the diff format that we were producing but we needed to improve it anyway.
This makes unified diff lines a little bit more `patch` compatible.
Also I tried to introduce a unit test to check this but couldn't decide which of the following to implement:
1. Should I replace `println` macros with `Writer`s? And access the produced output within a test?
2. Should I add an external test (something like `src/test/run-pass/command-exec.rs`)
3. There are crates that capture `stdout`. Are they safe to use here? (I don't think so)

Use the trait-environment+type as the key. Note that these
are only invoked on types that live for the entire compilation

bits and caches that were in place before.
