ed1b78c16b Move unicode Python script into libstd_unicode crate.
The only place this Python script is used is inside the libstd_unicode
crate, so lets move it there.

Run non-native tests on real device

After #40733, I've made some hacks to the QEMU client-server tools to allow running the tests on a real device when cross compiling Rust. The address and port of the remote server can be set using an environment variable.

I've made this mainly for local testing purposes, if you're interested in merging this, I'd clean it a bit more (eg. renaming the functions from `qemu-` to something else). I'm not asking for CI integration or adding ARM boards to the build system; it's just that I used these modifications and I was wondering if you'd find them useful too.

Remove obsolete --disable-elf-tls configure switch.

Support for disabling ELF-style thread local storage in
the standard library at configure time was removed in
pulls #30417 and #30678, in favour of a member in
the TargetOptions database. The new mentod respects
MACOSX_DEPLOYMENT_TARGET on macOS, addressing the
original use case for this configure optionl

However, those commits left the configure option itself
in place. It's no longer referenced anywhere and can
be removed.

ac46091e82 Auto merge of #41733 - nikomatsakis:incr-comp-remove-ast-ty-to-ty-cache, r=eddyb
Remove ast-ty-to-ty cache

As discussed on IRC, this basically just removes the cache, and rewrites rustdoc and save-analysis so call into the astconv code. It *might* make sense for this to be a more fine-grained query, but that would (at least) require us to be using `HirId` and not `NodeId`.

(Perhaps I should open a FIXME?)

I didn't measure perf impact (yet?). I did observe that the cache seems to hit *rarely* -- and only in between items (I experimented with a cache "per def-id", but that had zero hits). In other words, every single hit on the cache is a dependency bug, since it is "shuttling" information between items without dependency edges.

Fix @martinhath's mailmap entry

I stumbled upon a name duplication issue in [rust-lang-nursery/thanks](https://github.com/rust-lang-nursery/thanks/), and realized that this problem is easily fixable. I've (hopefully) done the right thing here. It works locally (`git shortlog | grep "Thoresen"` only returns one entry instead of two).

I didn't bother creating an issue in the `thanks` repository, since I did the `.mailmap` editing myself.

Add -march=armv7-a parameter to armv7 android linker

Without this option, the linker fails to link any library that uses `std::future`. The error points some undefined references, like `std::__future_base::_Result_base`.

For example, it fails to link rustc because llvm 4.0 uses `std::future`.

Consider changing to & for let bindings #40402

This is a fix for #40402

For the example
```
fn main() {
    let v = vec![String::from("oh no")];

    let e = v[0];
}
```

It gives
```
error[E0507]: cannot move out of indexed content
 --> ex1.rs:4:13
  |
4 |     let e = v[0];
  |             ^^^^ cannot move out of indexed content
  |
  = help: consider changing to `&v[0]`

error: aborting due to previous error
```

Another alternative is
```
error[E0507]: cannot move out of indexed content
 --> ex1.rs:4:13
  |
4 |     let e = v[0];
  |             ^^^^ consider changing to `&v[0]`

```

rework the queries for the MIR pipeline

This PR refashions the MIR pipeline. There are a number of changes:

* We no longer have "MIR passes" and the pass manager is completely reworked. Unless we are doing the interprocedural optimization (meaning, right now, the inline pass), we will process a single MIR from beginning to finish in a completely on-demand fashion; i.e., when you request `optimized_mir(D)`, that will trigger the MIR for `D` to actually be built and optimized, but no other functions are built or touched.
* We no longer use `&'tcx RefCell<Mir<'tcx>>` as the result of queries, since that spoils the view of queries as "pure functions". To avoid however copying the MIR, we use a `&'tcx Steal<Mir<'tcx>>` -- this is something like a ref-cell, in that you can use `borrow()` to read it, but it has no `borrow_mut()`. Instead, it has `steal()`, which will take the contents and then panic if any further read attempt occurs.
* We now support `[multi]` queries, which can optionally yield not just one result but a sequence of (K, V) pairs. This is used for the inlining pass. If inlining is enabled, then when it is invoked on **any** def-id D, it will go and read the results for **all** def-ids and transform them, and then return the results for all of them at once. This isn't ideal, and we'll probably want to rework this further, but it seems ok for now (note that MIR inlining is not enabled by default).

**Tips for the reviewer:** The commits here are meant to build individually, but the path is a *bit* meandering. In some cases, for example, I introduce a trait in one commit, and then tweak it in a later commit as I actually try to put it to use. You may want to read the README in the final commit to get a sense of where the overall design is headed.

@eddyb I did not wind up adding support for queries that produce more than one *kind* of result. Instead, I decided to just insert judicious use of the `force()` command. In other words, we had talked about e.g. having a query that produced not only the MIR but also the `const_qualif` result for the MIR in one sweep. I realized you can also have the same effect by having a kind of meta-query that forces the const-qualif pass and then reads the result. See the README for a description. (We can still do these "multi-query results" later if we want, I'm not sure though if it is necessary.)

This is a breaking change. Does that imply any further process?

I am not sure whether I wrote that "compilation must fail"-test correctly, but at least it is passing here with the patch applied. Same for the `since = "1.18.0"`, I just picked it because I had to pick something.

See #41444. As a first step towards untangling `ParameterEnvironment`, change
its `caller_bounds` field from a `Vec` into an interned slice of

This change is intentionally well-contained and doesn't pull on any of the
loose ends. In particular, you'll note that `normalize_param_env_or_error`
now interns twice.
