Since it's inception a long time ago, the parallel compiler and its cfgs
have been a maintenance burden. This was a necessary evil the allow
iteration while not degrading performance because of synchronization
overhead.
But this time is over. Thanks to the amazing work by the parallel
working group (and the dyn sync crimes), the parallel compiler has now
been fast enough to be shipped by default in nightly for quite a while
now.
Stable and beta have still been on the serial compiler, because they
can't use `-Zthreads` anyways.
But this is quite suboptimal:
- the maintenance burden still sucks
- we're not testing the serial compiler in nightly
Because of these reasons, it's time to end it. The serial compiler has
served us well in the years since it was split from the parallel one,
but it's over now.
Let the knight slay one head of the two-headed dragon!

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Make `FatalErrorMarker` lower priority than other panics
This makes `FatalErrorMarker` lower priority than other panics in a parallel sections. If any other panics occur, they will be unwound instead of `FatalErrorMarker`. This ensures `rustc` will exit with the correct error code on ICEs.
This fixes https://github.com/rust-lang/rust/issues/116659.

This simplifies the expression, especially for the rayon part, and also
lets us drop the `E: Copy` constraint.
Avoid a `track_errors` by bubbling up most errors from `check_well_formed`2023-10-20T08:46:27+00:00Oli Scherergit-spam-no-reply9815368754983@oli-obk.de2023-10-18T08:47:17+00:00urn:sha1:fd9ef69adf631a96ffad2d777653ae2554909866Extract parallel operations in `rustc_data_structures::sync` into a new `parallel` submodule2023-09-06T07:47:34+00:00John Kåre Alsakerjohn.kare.alsaker@gmail.com2023-09-04T21:12:30+00:00urn:sha1:fe614712dded0a861fbcbf654663128318eb6dfb
