With these changes you can build a freestanding sysroot without using floating points using a Cargo.toml and copying the `deps` folder cargo outputs.
```
[package]
name = "sysroot"
version = "0.1.0"
[lib]
path = "lib.rs"
crate-type = ["rlib"]
[dependencies.core]
path = "../vendor/rust/src/src/libcore"
features = ["disable_float"]
[dependencies]
collections = { path = "../vendor/rust/src/src/libcollections" }
```
The standard library doesn't depend on rustc_bitflags, so move it to explicit
dependencies on all other crates. Additionally, the arena/fmt_macros deps could
be dropped from libsyntax.
Some struct members have a slighty different name on NetBSD. This has been
fixed in the libc crate, but not in libstd.
This also removes `st_spare` from MetadataExt, since it is private field
reserved for future use.
Android should use 64-bit LFS symbols for `lseek` and `ftruncate`, lest
those offset parameters suffer a lossy cast down to a 32-bit `off_t`.
Unlike GNU/Linux, Android's `stat`, `dirent`, and related functions are
always 64-bit LFS compatible, and `open` already implies `O_LARGEFILE`,
so all those don't need to follow Linux. It might be nice to unify them
anyway, but those other LFS symbols aren't present in API 18 bionic.

Right now the compiler's we're using actually default to armv7/thumb2 I believe,
so this should help push them back to what the arm-unknown-linux-* targets are
for. This at least matches that clang does for the `arm-unknown-linux-gnueabihf`
target which is to map it to an armv6 architecture.

I've made these unstable for now. Should they be stabilized straight away since we've had plenty of experience with people using the unstable intrinsics?
This warning was introduced on Nov 28, 2015 and got into 1.6 stable, it was later requalified from a hardwired warning to a warn-by-default lint.
If this patch is landed soon enough, then `match_of_unit_variant_via_paren_dotdot` will get into 1.8 stable as a deny-by-default lint.
My intention is to turn it into a hard error after March 3, 2016, then it will hit stable at 1.9.

Now that #31461 is merged, a failing resolution can never become indeterminate or succeed, so we no longer have to keep trying to resolve failing import directives.

This commit adds functionality that allows the name resolution pass
to search for entities (traits/types/enums/structs) by name, in
order to show recommendations along with the errors.
For now, only E0405 and E0412 have suggestions attached, as per the
request in bug #21221, but it's likely other errors can also benefit
from the ability to generate suggestions.
In #31717 we rebased our LLVM fork over the 3.8 release branch, and it was
thought that this fixed#31702. The testing, however, must have been erroneous,
as it unfortunately didn't fix the issue! Our MUSL nightly builders are failing
from the same assertion reported in the issue, so we at least know the test case
is a reproduction!
I believe the failure is only happening on the MUSL nightly builders because
none of the auto builders have LLVM assertions enabled, and the Linux nightly
builder *does* have assertions enabled for the binaries we generate but the
distcheck run doesn't test a compiler with LLVM assertions enabled.
It's unclear to me whether this test failing under valgrind is actually legit.
The test only fails in valgrind when everything is dynamically linked, and it
appears to work when statically linked.
For now just add the `// no-prefer-dynamic` directive and let's just chalk it up
to a weird valgrind issue.
Closes#31328
