0ac465924e Add line numbers and columns to error messages spanning multiple files
If an error message is emitted that spans several files, only the
primary file currently has line and column data attached. This is
useful information, even in files other than the one in which the error
occurs. We can often work out which line and column the error
corresponds to in other files — in this case it is helpful to add them
(in the case of ambiguity, the first relevant line/column is picked,
which is still helpful than none).

9e6ed17c4f make Command.argv Send on unix platforms
Implementing Send for a specific field rather than the whole struct is
safer: if a field is changed/modified and becomes non-Send, we can catch
it.

Using the len of the iterator doesn't give the same result.

We can't use git commands to compute a prerelease version when we're
building from a source tarball, or if git is otherwise unavailable.
We'll just call such builds `x.y.z-beta`, without a prerelease.

Unstable sort was added recently, and the code that is being modified is 3 years old. As quicksort doesn't allocate it will likely perform as well as, or better than linear search.

Teach rustc about DW_AT_noreturn and a few more DIFlags

We achieve two small things with this PR:
1. We provide definitions for a few additional llvm debuginfo flags
1. We _use_ one of these new flags, `FlagNoReturn`, and add it to debuginfo for functions with the never return type (`!`).

502de01ff4 rustc: SIMD types use pointers in Rust's ABI
This commit changes the ABI of SIMD types in the "Rust" ABI to unconditionally
be passed via pointers instead of being passed as immediates. This should fix a
longstanding issue, #44367, where SIMD-using programs ended up showing very odd
behavior at runtime because the ABI between functions was mismatched.

As a bit of a recap, this is sort of an LLVM bug and sort of an LLVM feature
(today's behavior). LLVM will generate code for a function solely looking at the
function it's generating, including calls to other functions. Let's then say
you've got something that looks like:

```llvm
define void @foo() { ; no target features enabled
  call void @bar(<i64 x 4> zeroinitializer)
  ret void
}

define void @bar(<i64 x 4>) #0 { ; enables the AVX feature
  ...
}
```

LLVM will codegen the call to `bar` *without* using AVX registers becauase `foo`
doesn't have access to these registers. Instead it's generated with emulation
that uses two 128-bit registers. The `bar` function, on the other hand, will
expect its argument in an AVX register (as it has AVX enabled). This means we've
got a codegen problem!

Comments on #44367 have some more contexutal information but the crux of the
issue is that if we want SIMD to work in general we'll need to ensure that
whenever a function calls another they ABI of the arguments being passed is in
agreement.

One possible solution to this would be to insert "shim functions" where whenever
a `target_feature` mismatch is detected the compiler inserts a shim function
where you pass arguments via memory to the shim and then the shim loads the
values and calls the target function (where the shim and the target have the
same target features enabled). This unfortunately is quite nontrivial to
implement in rustc today (especially when accounting for function pointers and
such).

This commit takes a different solution, *always* passing SIMD arguments through
memory instead of passing as immediates. This strategy solves the problem at the
LLVM layer because the ABI between two functions never uses SIMD registers. This
also shouldn't be a hit to performance because SIMD performance is thought to
often rely on inlining anyway, where a `call` instruction, even if using SIMD
registers, would be disastrous to performance regardless. LLVM should then be
more than capable of fixing all our memory usage to use registers instead after
enough inlining has been performed.

Note that there's a few caveats to this commit though:

* The "platform intrinsic" ABI is omitted from "always pass via memory". This
  ABI is used to define intrinsics like `simd_shuffle4` where LLVM and rustc
  need to have the arguments as an immediate.

* Additionally this commit does *not* fix the `extern` ("C") ABI. This means
  that the bug in #44367 can still happen when using non-Rust-ABI functions. My
  hope is that before stabilization we can ban and/or warn about SIMD types in
  these functions (as AFAIK there's not much motivation to belong there anyway),
  but I'll leave that for a later commit and if this is merged I'll file a
  follow-up issue.

All in all this...

Closes #44367
