Remove a stack frame from .await calls
The stack frames when `.await`ing one async fn from another currently look like this:
```
12: foo:🅱️:{{closure}}
at src/main.rs:2
13: <core::future::from_generator::GenFuture<T> as core::future::future::Future>::poll
at /home/sfackler/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/future/mod.rs:66
14: core::future::poll_with_context
at /home/sfackler/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src/libcore/future/mod.rs:84
15: foo:🅰️:{{closure}}
at src/main.rs:6
```
Since the move away from using TLS to pass the Context around, it's now easy to remove frame 14 by removing poll_with_context in favor of calling Future::poll directly. This still leaves the `GenFuture` frame, but that seems significantly harder to deal with.
It also improves diagnostics a bit since they no longer talk about the private poll_with_context function.

Add illumos triple
This fixesrust-lang/rust#55553 and adds support for `illumos` as a `target_os` on `x86_64`. In addition to the compile spec and libstd additions, several library dependencies have been bumped in order to permit working builds of cargo and rustup for the new target.
Work originally started by @jasonbking, with subsequent additions by @pfmooney and @jclulow.
Improve rustdoc source code a bit
Very small clean up. I realized that there were too many nested conditions whereas we could just use `and_then`.

End cleanup on rustdoc-js tools
Fixes#70689.
It removes a lot of code, which is pretty nice. :3
We now only have one entry point and a small set of options.

Fixes#71114
Renamed the struct to make it a little clearer that it doesn't just hold one
imports map. (I couldn't bring myself to write it as `ThinLTOImportsExports`
though, mainly since the exports map is literally derived from the imports map
data.) Added some doc to the struct too.
Revised comments to add link to the newer issue that discusses why the exports
are relevant.
Renamed a few of the methods so that the two character difference is more
apparent (because 1. the method name is shorter and, perhaps more importantly,
the changed characters now lie at the beginning of the method name.)
The `FnAbi` now knows if the function is allowed to unwind. If a
function isn't allowed to unwind, we can use a `call` instead of an
`invoke`.
This resolves an issue when calling LLVM intrinsics which cannot unwind
LLVM will generate an error if you attempt to invoke them so we need to
ignore cleanup blocks in codegen and generate a call instead.
Entirely remove `DUMMY_HIR_ID`
Some helpers functions have been introduced to deal with (buggy) cases
where either a `NodeId` or a `DefId` do not have a corresponding `HirId`.
Those cases are tracked in issue #71104.
