Auto merge of #23028 - Munksgaard:get_attrs_opt, r=eddyb
This is more flexible and less error-prone. `get_attrs` and
`get_attrs_opt` can be used on many more items than the old `get_attrs`
could.
This is all courtesy of @huonw, and directly taken from here:
https://github.com/rust-lang/rust/pull/22348/files#diff-0f85fcb07fb739876892e633fa0e2be6R5575
Also thanks to @Manishearth for pointing it out to me.
Also updates test for `plugin_registrar` to make it clear that
it is only testing the `plugin_registrar` feature gate.
Cc #22820. (Latter is not fixed, since there are still a bunch more feature-gates that need tests. But I wanted to stop here and move on to something else.)
Rollup merge of #23105 - alexcrichton:rand-wrapping, r=brson
There was a buildbot failure recently of an arithmetic overflow in the isaac
module of the rand crate, so I've imported the isaac implementation from
out-of-tree which makes somewhat more liberal usage of the wrapping primitives.
Hopefull this quelches any future overflow!

Rollup merge of #23202 - shepmaster:intro-threads-not-concurrent, r=steveklabnik
If we end the `scoped` call with a semicolon, the `JoinGuard` will be
dropped and not returned from the `map`. The thread will start up and
we immediately block, making for a very expensive sequential loop.
Rollup merge of #23210 - richo:rust-o, r=alexcrichton
rustc will ICE if you specify an outfile path that is bare without a
directory. As a workaround, before this -o ./foo will work
It wasn't clear to me where I could put a test that actually invokes rustc from a shell, although I think I can add doctests to that machinery in librustc_driver that will arrange for this to be called with arguments that would trigger the ICE

Right now the rust upgrade in cargo is blocked on fixing this overflow. If a
this benchmark is run it will trigger an overflow error today:
#[bench]
fn foo(b: &mut test::Bencher) {}
This commit adds a check on each iteration of the loop that the maximum
multiplier (10) doesn't overflow, and if it does just return the results so far.

Auto merge of #23137 - kmcallister:derive-sugar, r=sfackler
This is a hack, but I don't think we can do much better as long as `derive` is running at the syntax expansion phase.
If the `custom_derive` feature gate is enabled, this works with user-defined traits and syntax extensions. Without the gate, you can't use e.g. `#[derive_Clone]` directly, so this does not change the stable language.
To make this effective, we now check gated attributes both before and after macro expansion. This uncovered a number of tests that were missing feature gates.
This PR also cleans up the deriving code somewhat, and forbids some previously-meaningless attribute syntax. For this reason it's technically a
