compiletest: autoremove duplicate .nll.* files (#51204)
UI tests in bless mode should now check to see if `.nll.*` files have a
matching `.*` file. If a match is found, it will be deleted.
This should be extensible to other modes (i.e., Polonius).
On running with `--bless`, the two files removed in #51186 are, in turn,
removed automatically.

Fix building rustc on and for musl hosts.
This fixes all problems I had when trying to compile rustc on a musl-based distribution (with `crt-static = false` in `config.toml`).
This is a fixed version of what ended up being #50105, making it possible to compile rustc on musl targets.
The differences to the old (now merged and subsequently reverted) pull request are:
- The commit (6d9154a830) that caused the regression for which the original commits were reverted in #50709 is left out. This means the corresponding bug #36710 is still not fixed with `+crt-static`.
- The test for issue 36710 is skipped for musl targets (until the issue is properly fixed).
- Building cargo-vendor if `crt-static = false` is needed was broken (cargo-vendor links to some shared libraries if they exist on the system and this produces broken binaries with `+crt-static`)

While we're at it update the `backtrace` crate from crates.io. It turns out that
the submodule's configure script has gotten a lot more finnicky as of late so
also switch over to using the `cc` crate manually which allows to avoid some
hacks around the configure script as well
Add target for Big-endian ARM Cortex-R4F/R5F MCUs
The ARM Real-Time (‘R’) profile provides high-performing processors for safety-critical environments.
Cortex-R has ARM, Thumb instruction whereas Cortex-M makes use of Thumb only.
CI/Dockerfile is intentionally in the `disabled` folder.
Switch to bootstrapping from 1.27
It's possible the Float trait could be removed from core, but I couldn't tell whether it was intended to be removed or not. @SimonSapin may be able to comment more here; we can presumably also do that in a follow up PR as this one is already quite large.
- The output of each test is now in its own directory.
- "auxiliary" output is now under the respective test directory.
- `stage_id` removed from filenames, and instead placed in the stamp file as a hash. This helps keep path lengths down for Windows.
In brief, the new layout looks like this:
```
<build_base>/<relative_dir>/<testname>.<revision>.<mode>/
stamp
<testname>.err
<testname>.out
a (binary)
auxiliary/lib<auxname>.dylib
auxiliary/<auxname>/<auxname>.err
auxiliary/<auxname>/<auxname>.out
```
(revision and mode are optional)

tidy: Add a check for empty UI test files
Check for empty `.stderr` and `.stdout` files in UI test directories.
Empty files could still pass testing for `compile-pass` tests with no output
so they can get into the repo accidentally, but they are not necessary and can
be removed.
This is very much an in progress pull request. I'm having an issue with rustfmt. It wanted to reformat the entire file for almost every file by default. And when I run tidy it just errors out because it catches the empty files that are already in the repo.
My next step is goin got be to remove those empty file and see if running tidy again will actually reformat things outside of the context of `cargo fmt`
