ebec55406b Auto merge of #37824 - jseyfried:symbols, r=eddyb 
Clean up `ast::Attribute`, `ast::CrateConfig`, and string interning

This PR
 - removes `ast::Attribute_` (changing `Attribute` from `Spanned<Attribute_>` to a struct),
 - moves a `MetaItem`'s name from the `MetaItemKind` variants to a field of `MetaItem`,
 - avoids needlessly wrapping `ast::MetaItem` with `P`,
 - moves string interning into `syntax::symbol` (`ast::Name` is a reexport of `symbol::Symbol` for now),
 - replaces `InternedString` with `Symbol` in the AST, HIR, and various other places, and
 - refactors `ast::CrateConfig` from a `Vec` to a `HashSet`.

84415ea1f2 [LLVM 4.0] Set EH personality when resuming stack unwinding 
To resume stack unwinding, the LLVM `resume` instruction must be used.

In order to use this instruction, the calling function must have an
exception handling personality set.

LLVM 4.0 adds a new IR validation check to ensure a personality is
always set in these cases.

This was introduced in [r277360](https://reviews.llvm.org/rL277360).

c8867f8b46 Auto merge of #37672 - japaric:msp430, r=alexcrichton 
enable the MSP430 LLVM backend

to let people experiment with this target out of tree.

The MSP430 architecture is used in 16-bit microcontrollers commonly used
in Digital Signal Processing applications.

---

How this was tested:

Declaring a custom target with the following specification:

``` json
{
  "arch": "msp430",
  "data-layout": "e-m:e-p:16:16-i32:16:32-a:16-n8:16",
  "executables": true,
  "linker": "msp430-gcc",
  "llvm-target": "msp430",
  "max-atomic-width": 0,
  "no-integrated-as": true,
  "os": "none",
  "panic-strategy": "abort",
  "relocation-model": "static",
  "target-endian": "little",
  "target-pointer-width": "16"
}
```

And this minimal file:

``` rust

pub fn start() -> ! {
    loop {}
}

trait Copy {}

trait Sized {}
```

Produces the following object files:

```
$ rustc --target=msp430 --emit=obj foo.rs

$ msp430-objdump -Cd foo.o

foo.o:     file format elf32-msp430

Disassembly of section .text.start:

00000000 <start>:
   0:   21 83           decd    r1
   2:   00 3c           jmp     $+2             ;abs 0x4
   4:   00 3c           jmp     $+2             ;abs 0x6
   6:   ff 3f           jmp     $+0             ;abs 0x6

$ rustc --target=msp430 --emit=obj foo.rs -O

$ msp430-objdump -Cd foo.o

foo.o:     file format elf32-msp430

Disassembly of section .text.start:

00000000 <start>:
   0:   ff 3f           jmp     $+0             ;abs 0x0
```

~~TODO get this working with Makefiles so nightly releases include this backend~~
~~TODO measure the increase in binary size~~ +187KiB (+0.47%)
