ci: remove 32-bit Apple targets
This PR drops the `i686-apple` and `dist-i686-apple` CI builders, as well as removing the `armv7-apple-ios`, `armv7s-apple-ios` and `i386-apple-ios` targets from the `x86_64-apple` CI builder.
The change was approved in [RFC 2837](https://github.com/rust-lang/rfcs/pull/2837), and it should land in Rust 1.42 stable (so this cycle).

Fix ICE in const pretty printing and resolve FIXME
Consts now have a `fmt::Display` impl, so we can just use that to pretty-print.
This resolves an ICE in https://github.com/rust-lang/rust/issues/61936, though it hits more ICEs afterwards. I couldn't find a test case that was resolved by this that didn't hit errors later on.
Handle multiple error fix suggestions carefuly
The existing code seems to assume that substitutions spans are disjoint,
which is not always the case.
In the example:
pub trait AAAA {}
pub trait B {}
pub trait C {}
pub type T<P: AAAA + B + C> = P;
, we get three substituions starting from ':' and ending respectively at
the end of each trait token.
With the former offset calculation, this would cause `underline_start` to
eventually become negative before being converted to `usize`...
The new version may report erroneous results for non perfectly overlapping
substitutions but I don't know if such examples exist. Alternatively, we
could detect these cases and trim out overlapping substitutions.
Fixes#67690
Add an unstable conversion from thread ID to u64
We see multiple cases inside rustc and ecosystem code where ThreadId is
transmuted to u64, exploiting the underlying detail. This is suboptimal
(can break unexpectedly if we change things in std).
It is unlikely that ThreadId will ever need to be larger than u64 --
creating even 2^32 threads over the course of a program is quite hard,
2^64 is even harder. As such, we do not choose to return a larger sized
type (e.g. u128). If we choose to shrink ThreadId in the future, or
otherwise change its internals, it is likely that a mapping to u64 will
still be applicable (though may become more complex).
I will file a tracking issue as soon as this is loosely approved.
Standard library support for riscv64gc-unknown-linux-gnu
Add std support for RISC-V 64-bit GNU/Linux and update libc for RISC-V support.
