Deprecate `Vec::remove_item`
In #40062 we decided to remove that method. In #71834 it was said that we want to deprecate it for a few cycles before removing it. That's what this PR does.

Refactor hir::Place
For the following code
```rust
let c = || bar(foo.x, foo.x)
```
We generate two different `hir::Place`s for both `foo.x`.
Handling this adds overhead for analysis we need to do for RFC 2229.
We also want to store type information at each Projection to support
analysis as part of the RFC. This resembles what we have for
`mir::Place`
This commit modifies the Place as follows:
- Rename to `PlaceWithHirId`, where there `hir_id` is that of the
expressioin.
- Move any other information that describes the access out to another
struct now called `Place`.
- Removed `Span`, it can be accessed using the [hir
API](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/hir/map/struct.Map.html#method.span)
- Modify `Projection` to be a strucutre of its own, that currently only
contains the `ProjectionKind`.
Adding type information to projections wil be completed as part of https://github.com/rust-lang/project-rfc-2229/issues/5
Closes https://github.com/rust-lang/project-rfc-2229/issues/3

compiletest: Add directives to detect sanitizer support
Add needs-sanitizer-{address,leak,memory,thread} directive indicating
that test requires target with support for specific sanitizer.
This is an addition to the existing needs-sanitizer-support directive
indicating that test requires a sanitizer runtime library.
The existing needs-sanitizer-support directive could be incorporated into the
new ones, but I decided to retain it, since it enables running sanitizer
codegen tests even when building of sanitizer runtime libraries is disabled.

Implement new gdb/lldb pretty-printers
Reopened #60826
This PR replaces current gdb and lldb pretty-printers with new ones that were originally written for [IntelliJ Rust](https://github.com/intellij-rust/intellij-rust/tree/master/prettyPrinters).
The current state of lldb pretty-printers is poor, because [they don't use synthetic children](https://github.com/rust-lang/rust/issues/55586#issuecomment-436610063). When I started to reimplement lldb pretty-printers with synthetic children support, I've found current version strange and hard to support. I think `debugger_pretty_printers_common.py` is overkill, so I got rid of it.
The new pretty-printers have to support all types supported by current pretty-printers, and also support `Rc`, `Arc`, `Cell`, `Ref`, `RefCell`, `RefMut`, `HashMap`, `HashSet`.
Fixes #56252

Stabilize Option::zip
This PR stabilizes the following API:
```rust
impl<T> Option<T> {
pub fn zip<U>(self, other: Option<U>) -> Option<(T, U)>;
}
```
This API has real world usage as seen in <https://grep.app/search?q=-%3E%20Option%3C%5C%28T%2C%5Cs%3FU%5C%29%3E®exp=true&filter[lang][0]=Rust>.
The `zip_with` method is left unstably as this API is kinda niche
and it hasn't received much usage in Rust repositories on GitHub.

Clean up type alias impl trait implementation
- Removes special case for top-level impl trait
- Removes associated opaque types
- Forbid lifetime elision in let position impl trait. This is consistent with the behavior for inferred types.
- Handle lifetimes in type alias impl trait more uniformly with other parameters

Enable AVR as a Tier 3 target upstream
Tracking issue: #44052.
Things intentionally left out of the initial upstream:
* The `target_cpu` flag
I have made the cleanup suggestions by @jplatte and @jplatte in https://github.com/avr-rust/rust/commit/043550d9db0582add42e5837f636f61acb26b915.
Anybody feel free to give the branch a test and see how it fares, or make suggestions on the code patch itself.

Track span of function in method calls, and use this in #[track_caller]
Fixes #69977
When we parse a chain of method calls like `foo.a().b().c()`, each
`MethodCallExpr` gets assigned a span that starts at the beginning of
the call chain (`foo`). While this is useful for diagnostics, it means
that `Location::caller` will return the same location for every call
in a call chain.
This PR makes us separately record the span of the function name and
arguments for a method call (e.g. `b()` in `foo.a().b().c()`). This
`Span` is passed through HIR lowering and MIR building to
`TerminatorKind::Call`, where it is used in preference to
`Terminator.source_info.span` when determining `Location::caller`.
This new span is also useful for diagnostics where we want to emphasize
a particular method call - for an example, see
https://github.com/rust-lang/rust/pull/72389#discussion_r436035990

Make `PolyTraitRef::self_ty` return `Binder<Ty>`
This came up during review of #71618. The current implementation is the same as a call to `skip_binder` but harder to audit. Make it preserve binding levels and add a call to `skip_binder` at all use sites so they can be audited as part of #72507.

Allow tests to use
// ignore-remote
to ignore the test when using remote-test-{client,server}. In most
situations this would be covered by
// ignore-cross-compile
but I see no reason that a non-cross compiled remote test runner
shouldn't work.

There was an unused verbose command line argument. Add some prints if
verbose is set.
|
|
Some tests (e.g. ui-fulldeps/create-dir-all-bare.rs) assume that
RUST_TEST_TMPDIR exists on the system running the test. Expand
remote-test-{server,client} such that a tmp directory is created on the
remote runner and this environment variable will point at it.

Make remote-test-client and remote-test-server compatible with windows
`compiletest` and `remote-test-client`:
The command line for `remote-test-client` was changed slightly to allow cross-platform compatible paths. The old way of supplying the support libs was by joining their paths with the executable path
with `:`. This caused Windows-style paths to be split after the directory letter. Now, the number of support libs is provided as a parameter as well, and the support lib paths are split off from the regular args in the client.
`remote-test-server`:
- Marked Unix-only parts as such and implemented Windows alternatives
- On Windows `LD_LIBRARY_PATH` doesn't exist. Libraries are loaded from `PATH` though, so that's the way around it.
- Tiny cleanup: `Command::args`/`envs` instead of manually looping over them
- The temp path for Windows has to be set via environment variable, since there isn't a global temp directory that would work on every machine (as a static string)
