Remove potential cfgs duplicates
Fixes https://github.com/rust-lang/rust/issues/66921.
Before going any further (the issue seems to be linked to metadata as far as I can tell). Do you think this is the good place to do it or should it be done before?
r? @eddyb
As discussed in https://github.com/rust-lang/rust/issues/10184
Currently, casting a floating point number to an integer with `as` is Undefined Behavior if the value is out of range. `-Z saturating-float-casts` fixes this soundness hole by making `as` “saturate” to the maximum or minimum value of the integer type (or zero for `NaN`), but has measurable negative performance impact in some benchmarks. There is some consensus in that thread for enabling saturation by default anyway, but provide an `unsafe fn` alternative for users who know through some other mean that their values are in range.

Update the revision of wasi-libc used in wasm32-wasi
This commit updates the `wasi-libc` repository used to build the
wasm32-wasi target's libstd to ensure that both libstd and libc are
using the same wasi snapshot version.
Fix fetching arguments on the wasm32-wasi target
Fixes an error introduced in #66750 where wasi executables always think
they have zero arguments because one of the vectors returned here
accidentally thought it was length 0.
Add long error for E0631 and update ui tests.
This PR adds a long error for `E0631`, which covers errors where closure argument types are mismatched. It also updates UI tests where this error is applicable.
Part of #61137
[CI] fix the `! isCI` check in src/ci/run.sh
Using `if [ ! isCI ] || ...` doesn't run any command, just tests `isCI`
as a string, whereas `if ! isCI || ...` will actually run the `isCI`
command and negate its exit status.
std:win: avoid WSA_FLAG_NO_INHERIT flag and don't use SetHandleInformation on UWP
This flag is not supported on Windows 7 before SP1, and on windows server 2008 SP2. This breaks Socket creation & duplication.
This was fixed in a previous PR. cc #26658
This PR: cc #60260 reuses this flag to support UWP, and makes an attempt to handle the potential error.
This version still fails to create a socket, as the error returned by WSA on this case is WSAEINVAL (invalid argument). and not WSAEPROTOTYPE.
