std: Link to gcc_s on NetBSD
Currently the nightlies we're producing fail when linking some C code into a
Rust application with the error message:
libgcc_s.so.1: error adding symbols: DSO missing from command line
By linking `gcc_s` instead of `gcc` this error goes away. I haven't tested this
on NetBSD itself, but should help get the Linux cross-compile image moreso up
and working!
Rollup merge of #32342 - petevine:patch-1, r=alexcrichton
Use explicit -march flags in the i586 mk file
`-march` should definitely go last, after the environment `$C(XX)FLAGS`, or it's going to remain brittle.
This should fix cross-compilation issues on x86_64 (possibly x86 too on some newer distros) - it was far too assuming of me to expect you really had to want i586 using your own flags.

Fix usability problem when browse document locally
You cannot use `history.replaceState` when you browse locally, it breaks the security policy of Chrome and perhaps other browsers.
Closes https://github.com/rust-lang/rust/issues/32307
Thank @crumblingstatue for the help!

syntax: impl ToTokens for P<ast::ImplItem>
I'm working on updating zinc for latest rust, and it appears that I need this impl[0].
More generally, I realise that libsyntax is "Whatever the compiler team needs to build a compiler", but should I just open a PR fleshing this out for all types?

Add intrinsics for float arithmetic with `fast` flag enabled
Add intrinsics for float arithmetic with `fast` flag enabled
`fast` a.k.a UnsafeAlgebra is the flag for enabling all "unsafe"
(according to llvm) float optimizations.
See LangRef for more information http://llvm.org/docs/LangRef.html#fast-math-flags
Providing these operations with less associativity rules (for example)
is useful to numerical applications.
For example, the summation loop:
let sum = 0.;
for element in data {
sum += *element;
}
Using the default floating point semantics, this loop expresses that the
floats must be added in a sequence, one after another. This constraint
is usually completely unintended, and it means that no auto-vectorization
is possible.

derive: Avoid emitting provided PartialEq, PartialOrd methods for c-like enums
derive: Avoid emitting provided PartialEq, PartialOrd method for c-like enums
`ne` is completely symmetrical with the method `eq`, and we can save
rust code size and compilation time here if we only emit one of them
when possible.
One case where it's easy to recognize is when it's a C-like enum. Most
other cases can not omit ne, because any value field may have a custom
PartialEq implementation.

Auto merge of #32282 - sfackler:panic-hook, r=alexcrichton
Adjustments to the panic hook API
Rename `set_handler` and `take_handler` to `set_hook` and `take_hook` since we're not actually "handling" (i.e. fixing) anything.
Also alter `set_hook` to take a `Box<Fn(&PanicInfo) + 'static + Sync + Send>` rather than a parameterized closure since there's otherwise no easy way to re-register a hook that came from `take_hook`.

Refactor call & function handling in trans, enable MIR bootstrap.
Non-Rust and Rust ABIs were combined into a common codepath, which means:
* The ugly `__rust_abi` "clown shoes" shim for C->Rust FFI is gone, fixes #10116.
* Methods, *including virtual ones* support non-Rust ABIs, closes #30235.
* Non-Rust ABIs also pass fat pointers in two arguments; the result should be identical.
* Zero-sized types are never passed as arguments; again, behavior shouldn't change.
Additionally, MIR support for calling intrinsics (through old trans) was implemented.
Alongside assorted fixes, it enabled MIR to launch :rocket: and do a *complete* bootstrap.
To try it yourself, `./configure --enable-orbit` *or* `make RUSTFLAGS="-Z orbit"`.
