Rollup merge of #67054 - RalfJung:set-discriminant-unreachable, r=oli-obk
codegen "unreachable" for invalid SetDiscriminant

Follow-up from https://github.com/rust-lang/rust/pull/66960. I also realized I don't understand our policy for using `abort` vs `unreachable`. AFAIK `abort` is safe to call and just aborts the process, while `unreachable` is UB. But sometimes we use both, like here

d825e35ee8/src/librustc_codegen_ssa/mir/block.rs (L827-L828)

and here

d825e35ee8/src/librustc_codegen_ssa/mir/block.rs (L264-L265)

The second case is even more confusing because that looks like an unreachable `return` to me, so why would we codegen a safe abort there?

Rollup merge of #67033 - cuviper:ValueName2, r=rkruppe
Migrate to LLVM{Get,Set}ValueName2

The deprecated `LLVM{Get,Set}ValueName` only work with NUL-terminated
strings, but the `2` variants use explicit lengths, which fits better
with Rust strings and slices. We now use these in new helper functions
`llvm::{get,set}_value_name` that convert to/from `&[u8]`.

Closes #64223.

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

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.

Include a span in more `expected...found` notes

In most places, we use a span when emitting `expected...found` errors.
However, there were a couple of places where we didn't use any span,
resulting in hard-to-interpret error messages.

This commit attaches the relevant span to these notes, and additionally
switches over to using `note_expected_found` instead of manually
formatting the message

Reorganize borrow check diagnostic code

Currently borrow checker diagnostics are split across many different modules in different places in the `librustc_mir` crate. This moves them all to a `diagnostics` module. This also reduces the nesting of the modules a bit (sooo much nesting).

I am also thinking of moving stuff out of the `nll` module since we only have one borrow checker now (🎉), and maybe it even makes sense to split out all of this stuff to a `librustc_borrow_check`, but those are for the future. Feel free to ping me here or on zulip and let me know what you think...
