ba72d9722c Don't add unnamed address attributes to intrinsics. 
Intrinsics never have an address, so it doesn't make sense to say that their
address is unnamed.

3dd1a48f3f Auto merge of #27893 - nikomatsakis:mir, r=nrc 
This PR contains a new crate, `rustc_mir`, which implements the MIR as specified in the RFC (more or less). There are no targeted unit tests at the moment, as I didn't decide what kind of infrastructure would be best and didn't take the time to implement it. 

~~NB: In packaging up this PR, I realized that MIR construction code is not triggering for methods right now, I think it's only for fixed fns. I'll push a fix for this soon. Hopefully it doesn't stop any crates from building. :)~~ Fixed. Everything still seems to work.

However, the MIR construction code (`librustc_mir/build`) is intentionally quite distinct from the code which munges the compiler's data structures (`librustc_mir/tcx`). The interface between the two is the `HIR` trait (`librustc_mir/hir`). To avoid confusion with @nrc's work, perhaps a better name for this trait is warranted, although ultimately this trait *will* be connected to the HIR, I imagine, so in a way the name is perfect. Anyway, I'm open to suggestions. The initial motivation for this split was to allow for the MIR construction code to be unit-tested. But while I didn't end up writing unit tests (yet), I did find the split made the code immensely easier to think about, since the messiness of our existing system, with its myriad hashtables, punning, and so forth, is confined to one part, which simply transforms to a more fully explicit AST-like form. I tried to separate out the commits somewhat, but since this mostly new code, it mostly winds up coming in one fell swoop in the MIR commit.

Quick guide to the MIR crate:

- `repr.rs` defines the MIR itself; each MIR instance is parameterized by some HIR `H`
- `build/` is the MIR construction code, parameterized by a particular HIR
- `hir/` is the definition of the HIR interface
- `tcx/` is the impl of the HIR interface for the tcx
- `dump.rs` is the minimal compiler pass that invokes the HIR

One open question:

- In the HIR trait, I used exclusively struct-like variants. I found I like this more, since things have names. Should I convert the repr code?

a269e31a30 Auto merge of #28265 - boblehest:master, r=bluss 
In the last code snippet on the following page there is a bug in the
implementation of Vec::drain().

https://doc.rust-lang.org/nightly/nomicon/vec-drain.html

```rust
pub fn drain(&mut self) -> Drain<T> {
    // Oops, setting it to 0 while we still need the old value!
    self.len = 0;

    unsafe {
        Drain {
            // len is used to create a &[T] from &self here,
            // so we end up always creating an empty slice.
            iter: RawValIter::new(&self),
            vec: PhantomData,
        }
    }
}
```

A simple test to verify that Drain is broken can be found here:
https://play.rust-lang.org/?gist=30f579565e4bbf4836ce&version=nightly

And here's one with a fixed implementation:

6b36e921f4 Auto merge of #28242 - Diggsey:msvc-backtrace, r=alexcrichton 
Currently LLVM does not generate the debug info required to get complete backtraces even when functions are inlined, so that part of the `run-pass/backtrace-debuginfo.rs` test is disabled when targetting MSVC. At worst this results in missing stack frames where functions have been inlined.
