a213ff8299 Move numeric From and TryFrom impls to libcore/convert/num.rs
This makes `libcore/num/mod.rs` slightly smaller. It’s still 4911 lines and not easy to navigate. This doesn’t change any public API.

cba479f75c Add {f32,f64}::approx_unchecked_to<Int> unsafe methods
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.

Rollup merge of #67021 - elichai:2019-12-fmt, r=QuietMisdreavus
Fix docs for formatting delegations

If you use the example in the docs right now it breaks all the options Formatters have to offer.
i.e. https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=214392ecc6eff73b4789c32568395f72 this should've padded the output with 4 zeros but didn't.

with the new example it does work: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=3bdfb29f395230c5129c5f56dcfcb2a9

The only thing i'm not quite sure about is what's the right way to do it in a loop (altough non of the docs talk about it people are doing it in the wild and there were a couple of attempts to include in libcore)
i.e. https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=4c4dca3c90ba36779ecd014f3899ab9c

[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.

MSDN page for WSASocketW (that states the platform support for WSA_FLAG_NO_HANDLE_INHERIT): https://docs.microsoft.com/en-us/windows/win32/api/winsock2/nf-winsock2-wsasocketw
