Fix msvc-specific differences in debuginfo tests

As part of rust-lang#161657

Fixes ~every test that fails due to an msvc-specific problem. I tried to modify the `lldb-check` commands in-place where possible. If I couldn't, I used revisions.

There is 1 very tiny visualizer bug fix that I lumped in here that affects summaries of empty arrays on msvc (`]` -> `[]`)

`basic-types-globals.rs`- msvc stores globals under the `statics` category, and LLDB-with-PDB-debug-info requires that those be access by a fully qualified name (which shouldn't pose any issue for dwarf debug info, which IIRC can access via the qualified or unqualified name). I enforced the crate name through compiler flags, so even if this file moves around or is renamed, it shouldn't break.

The above also applies to `no_mangle-info.rs` except, for some reason, non-msvc targets are *only* able to access the top level static through the unqualified path. I'm not 100% sure if this is an LLDB bug or not, but it's not a huge deal for us since we can just use revisions.

The only test that changed behaviorally is `thread-names.rs`, which now uses a `script` command to print all threads, and then `compiletest` can pick the 2 it cares about out of that list. On windows, the spawned thread isn't thread 2, since there's typically a bunch of `ntdll.dll` threads. Even for non-windows, relying on exact thread numbers seems pretty fragile so this should help all around.

After this patch, the remainder of the 22 test failures on `windows-msvc` are the `<variable has been optimized out>` issue and the variable shadowing issue. The variable shadowing is a bug on their end, but we can work around it. I need to look into the `<variable has been optimized out>` issue a bit more to see what's going on there.

Rollup merge of rust-lang#160651 - rabindra789:fix/mir-verifier-move-…
c217fd3 
…call-args, r=WaffleLapkin

mir: validate `Move` call arguments are locals or box derefs

Fixes rust-lang#103362.

This PR adds a MIR validation check for `Move` arguments passed to `Call` and `TailCall` terminators.
A moved argument should be either a local or the contents of the `Box`. Other places can deinitialize memory that codegen does not track correctly. The check is only enabled with `-Zvalidate-mir`, using the same phase restriction as the existing `Copy` check.
Added a regression test covering the invalid case.

Rollup merge of rust-lang#161946 - nia-e:more-box-impls, r=clarfonthey
5df5032 
Generalise (most) impls on `Box`

Resolves the trait impl concern for rust-lang#156882; `Default` wasn't touched since changing that would be breaking, but hopefully all of this should be fine - I'll do a crater run to be sure. Certain impls that were for one reason or another Annoying to generalise (e.g. `Clone for Box<Path>`) were also untouched since I believe we can add those in the future, as they're on concrete types.

This existed to stop people from overriding some methods, but `final fn` exists now.

It's already being used in std here and there with no problems, so I figure it's fine to use in the compiler.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.

Attemped fix for home dir problem on `dist-aarch64-llvm-mingw`

This is a fix for this spurious failure, which seems to regularly happen lately
rust-lang#162550 (comment)

disclaimer: I have no clue what is causing this and that I'm just attacking the symptoms. Seems like some kind of github runner misconfiguration?
