ARM: expose the "mclass" target feature

This let us differentiate, in conditional compilation context, between ARM Cortex-M targets, like
the `thumbv*` targets, and other ARM targets, like the ARM Cortex-A Linux targets.

bors 99b0ddb88a Auto merge of #51656 - soc:topic/fix-home-dir, r=SimonSapin 
Deprecate `std::env::home_dir` and fix incorrect documentation

Compare `std::env::home_dir`s claim:

> Returns the value of the 'HOME' environment variable if it is set and not equal to the empty string.

... with its actual behavior:

```
std::env::set_var("HOME", "");
println!("{:?}", std::env::var_os("HOME")); // Some("")
println!("{:?}", std::env::home_dir());     // Some("")
```

The implementation is incorrect in two cases:
- `$HOME` is set, but empty.
- An entry for the user exists in `/etc/passwd`, but it's `pw_dir` is empty.

In both cases Rust considers an empty string to be a valid home directory. This contradicts the documentation, and is wrong in general.

bors a178cba9f1 Auto merge of #52021 - nikomatsakis:nll-region-errors, r=estebank 
refactor and cleanup region errors for NLL

This is a WIP commit. It simplifies some of the code from https://github.com/rust-lang/rust/pull/51536 and extends a few more steps towards the errors that @davidtwco and I were shooting for. These are intended as a replacement for the general "unable to infer lifetime" messages -- one that is actually actionable. We're certainly not there yet, but the overall shape hopefully gets a bit clearer.

I'm thinking about trying to open up an internals thread to sketch out the overall plan and perhaps discuss how to get the wording right, which special cases to handle, etc.
