[unix] Don't clone command-line args on startup

Fixes part of #47164 and simplifies the `args` code on non-Apple Unix platforms.

Note: This could change behavior for programs that use both `std::env::args` *and* unsafe code that mutates `argv` directly.  However, these programs already behave differently on different platforms.  The new behavior on non-Apple platforms is closer to the existing behavior on Apple platforms.

Minor rewrite of env::current_exe docs; clarify symlinks.

- Update example in ‘security’ section to use hard links, like the
  linked securityvulns.com example.
- Weaken language on symbolic links – indicate behavior is
  platform-specific

Fixes https://github.com/rust-lang/rust/issues/43617.

91611fc3d0 Let libpanic_abort call into libc's abort() on CloudABI.
Ideally, we should make use of CloudABI's internal proc_raise(SIGABRT)
system call. POSIX abort() requires things like flushing of stdios,
which may not be what we want under panic conditions. Invoking the raw
CloudABI system call would have prevented that.

Unfortunately, we have to make use of the "cloudabi" crate to invoke raw
CloudABI system calls. This is undesired, as discussed in the pull
request (#47190).

fcdca7f2da rustc: Don't ICE if we invalidate an invalid incr dir
This showed up on the Windows bot for testing this PR, and this pr allows
`mark_incr_comp_session_as_invalid` ok if it's already invalid, hopefully
avoiding scary ICEs and instead leaving the nicely printed errors

b719578f48 Use name-discarding LLVM context
This is only applicable when neither of --emit=llvm-ir or --emit=llvm-bc are not
requested.

In case either of these outputs are wanted, but the benefits of such context are
desired as well, -Zfewer_names option provides the same functionality regardless
of the outputs requested.

ff2f328d7e Rollup merge of #47162 - stjepang:cleanup-btreeset, r=alexcrichton
Remove `T: Ord` bound from `BTreeSet::{is_empty, len}`

This change makes the API for `BTreeSet` more consistent with `BTreeMap`, where `BTreeMap::{is_empty, len}` don't require `T: Ord` either.

Also, it reduces the number of `impl`s for `BTreeSet`, making the generated documentation look much cleaner. Closes #47138.

Span::resolved_at and Span::located_at to combine behavior of two spans

Proc macro spans serve two mostly unrelated purposes: controlling name resolution and controlling error messages. It can be useful to mix the name resolution behavior of one span with the line/column error message locations of a different span.

In particular, consider the case of a trait brought into scope within the def_site of a custom derive. I want to invoke trait methods on the fields of the user's struct. If the field type does not implement the right trait, I want the error message to underline the corresponding struct field.

Generating the method call with the def_site span is not ideal -- it compiles and runs but error messages sadly always point to the derive attribute like we saw with Macros 1.1.

```
  |
4 | #[derive(HeapSize)]
  |          ^^^^^^^^
```

Generating the method call with the same span as the struct field's ident or type is not correct -- it shows the right underlines but fails to resolve to the trait in scope at the def_site.

```
  |
7 |     bad: std:🧵:Thread,
  |     ^^^^^^^^^^^^^^^^^^^^^^^^
```

The correct span for the method call is one that combines the def_site's name resolution with the struct field's line/column.

```rust
field.span.resolved_at(Span::def_site())

// equivalently
Span::def_site().located_at(field.span)
```

Adding both because which one is more natural will depend on context.

26d129ce39 Rollup merge of #47110 - EdSchouten:cloudabi-tls, r=kennytm
Use the right TLS model for CloudABI.

CloudABI doesn't do dynamic linking. For this reason, there is no need
to handle any other TLS model than local-exec. CloudABI's C library
doesn't provide a __tls_get_addr() function to do Dynamic TLS.

By forcing local-exec to be used here, we ensure that we don't generate
function calls to __tls_get_addr().

016f7f49c2 Rollup merge of #47033 - EdSchouten:cloudabi-oom, r=kennytm
Disable printing of error message on file descriptor 2 on CloudABI.

As CloudABI is a capability-based runtime environment, file descriptors
are the mechanism that grants rights to a process. These file
descriptors may be passed into processes on startup using a utility
called cloudabi-run. Unlike the POSIX shell, cloudabi-run does not
follow the UNIX model where file descriptors 0, 1 and 2 represent stdin,
stdout and stderr. There can be arbitrary many (or few) file descriptors
that can be provided. For this reason, CloudABI's C library also doesn't
define STD*_FILENO. liblibc should also not declare these.

Disable the code in liballoc_system that tries to print error messages
over file descriptor 2. For now, let's keep this function quiet. We'll
see if we can think of some other way to log this in the future.

Correct a few stability attributes

* The extra impls for `ManuallyDrop` were added in #44310 which was only stabilised in 1.22.0.
* The impls for `SliceIndex` were stabilised in #43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable.
* The `From` impls for atomic integers were added in #45610 but most atomic integers are still unstable.
* The `shared_from_slice2` impls were added in #45990 but they won't be stable until 1.24.0.
* The `Mutex` and `RwLock` impls were added in #46082 but won't be stable until 1.24.0.

Allow non-alphabetic underscores in camel case

Certain identifiers, such as `X86_64`, cannot currently be unambiguously represented in camel case (`X8664`, `X86_64`, `X8_664`, etc. are all transformed to the same identifier). This change relaxes the rules so that underscores are permitted between two non-alphabetic characters under `#[forbid(non_camel_case_types)]`. Fixes #34633 and fixes #41621.

9a8f0a8cb0 Make libpanic_unwind build on CloudABI.
CloudABI uses LLVM's libunwind for stack unwinding. There was a small
bug that went by unnoticed, namely that it was not built with -fno-rtti.
This caused it to (indirectly) depend on the entire C++ runtime.

Now that that issue has been resolved, it is also perfectly fine to make
use of this library for programming languages other than C++.

Reword reason for move note

On move errors, when encountering an enum variant, be more ambiguous and do not refer to the type on the cause note, to avoid referring to `(maybe as std::prelude::v1::Some).0`, and instead refer to `the value`.

Sidesteps part of the problem with #41962:

```
error[E0382]: use of partially moved value: `maybe`

  |                     value moved here
  = note: move occurs because the value has type `std::vec::Vec<bool>`, which does not implement the `Copy` trait
