Fixes #24008.

Fixes #24173

Without the `box` keyword, one of these two reasons is not correct, so
let's just eliminate this section and elaborate on the reason for the
legit use case inline.

In 8f5b5f94dcdb9884737dfbc8efd893d1d70f0b14, `default::Default` was
added to the prelude, so these imports are no longer necessary.
|
|
Only backporting the style portion, as changing the test suite is needless churn, and the book/reference are getting their own imports at the end.

should just require that all regions are constrained, but that is more
of a breaking change.

This allows `io::Error` values to be stored in `Arc` properly.
Because this requires `Sync` of any value passed to `io::Error::new()`
and modifies the relevant `convert::From` impls, this is a

This commit removes all the old casting/generic traits from `std::num` that are
no longer in use by the standard library. This additionally removes the old
`strconv` module which has not seen much use in quite a long time. All generic
functionality has been supplanted with traits in the `num` crate and the
`strconv` module is supplanted with the [rust-strconv crate][rust-strconv].
[rust-strconv]: https://github.com/lifthrasiir/rust-strconv
This is a breaking change due to the removal of these deprecated crates, and the
alternative crates are listed above.

Words struct was stabilied by mistake. Unstabilize.

This is an implementation of [RFC 1030][rfc] which adds these traits to the
prelude and additionally removes all inherent `into_iter` methods on collections
in favor of the trait implementation (which is now accessible by default).
[rfc]: https://github.com/rust-lang/rfcs/pull/1030
This is technically a breaking change due to the prelude additions and removal
of inherent methods, but it is expected that essentially no code breaks in
practice.

This avoids various ICEs, e.g. premature calls to cat_expr that yield
the dreaded "cat_expr Errd" ICE.

Note: this Warns rather than error on shadowing problems involving labels.
We took this more conservative option mostly due to issues with
hygiene being broken for labels and/or lifetimes.
Add FIXME regarding non-hygienic comparison.

I doubt this PR is ready to merge as-is, for a couple reasons:
* There are no tests for this change. I'm not sure how to add tests for this change, as it modifies the C ABI for a cross-compilation target. Anecdotally, I have an iOS library I've been working on, and before this change, it crashes running on an arm64 device due to bad calling conventions (a simplified example is in #24154), and after this change, it runs correctly.
* This is my first foray into LLVM. I did my best to reimplement what Clang does for AArch64 codegen (https://github.com/llvm-mirror/clang/blob/master/lib/CodeGen/TargetInfo.cpp), particularly in `ABIInfo::isHomogeneousAggregate`, `AArch64ABIInfo::isHomogeneousAggregateBaseType`, and `AArch64ABIInfo::isHomogeneousAggregateSmallEnough`, but I'm not confident I got a complete translation, particularly because Clang includes a lot of checks that I don't believe are necessary for rustc.
Fixes #24154.

One of the parameters to the magical "register a thread-local destructor"
function is called `__dso_handle` and largely just passed along (this seems to
be what other implementations do). Currently we pass the *value* of this symbol,
but apparently the correct piece of information to pass is the *address* of the
symbol.
In a PIE binary the symbol actually contains an address to itself which is why
we've gotten away with what we're doing as long as we have. In a non-PIE binary
the symbol contains the address `NULL`, causing a segfault in the runtime
library if it keeps going.
Closes #24445

closes #24434
This PR changes executes `syntax::config::strip_unconfigured_items` before `syntax::feature_gate::check_crate_macros(sess.codemap()`. As far as I know, `strip_unconfigured_items` should be independent of `check_crate_macros`.

This is a little bit tricky, since with include_str!, we know that we
are including utf-8 content, so it's safe to store the source as a
String in a FileMap. We don't know that for include_bytes!, but I don't
think we actually need to track the contents anyways, so I'm passing "".
new_filemap does check for the zero length content, and it should be
reasonable, howeven I'm not sure if it would be better to pass None
instead of Some(Rc::new("")) as the src component of a FileMap.
Fixes bug #24348
