aba93c6b60 auto merge of #5966 : alexcrichton/rust/issue-3083, r=graydon
Closes #3083.

This takes a similar approach to #5797 where a set is present on the `tcx` of used mutable definitions. Everything is by default warned about, and analyses must explicitly add mutable definitions to this set so they're not warned about.

Most of this was pretty straightforward, although there was one caveat that I ran into when implementing it. Apparently when the old modes are used (or maybe `legacy_modes`, I'm not sure) some different code paths are taken to cause spurious warnings to be issued which shouldn't be issued. I'm not really sure how modes even worked, so I was having a lot of trouble tracking this down. I figured that because they're a legacy thing that I'd just de-mode the compiler so that the warnings wouldn't be a problem anymore (or at least for the compiler).

Other than that, the entire compiler compiles without warnings of unused mutable variables. To prevent bad warnings, #5965 should be landed (which in turn is waiting on #5963) before landing this. I figured I'd stick it out for review anyway though.

3d43af15d8 rustc: Anti-copy police
In this case, some copies are still necessary to convert from
a mutable to an immutable @-box. It's still an improvement,
I hope.

9963bd2413 Cleanup substitutions and treatment of generics around traits in a number of ways.
- In a TraitRef, use the self type consistently to refer to the Self type:
  - trait ref in `impl Trait<A,B,C> for S` has a self type of `S`.
  - trait ref in `A:Trait` has the self type `A`
  - trait ref associated with a trait decl has self type `Self`
  - trait ref associated with a supertype has self type `Self`
  - trait ref in an object type `@Trait` has no self type

- Rewrite `each_bound_traits_and_supertraits` to perform
  substitutions as it goes, and thus yield a series of trait refs
  that are always in the same 'namespace' as the type parameter
  bound given as input.  Before, we left this to the caller, but
  this doesn't work because the caller lacks adequare information
  to perform the type substitutions correctly.

- For provided methods, substitute the generics involved in the provided
  method correctly.

- Introduce TypeParameterDef, which tracks the bounds declared on a type
  parameter and brings them together with the def_id and (in the future)
  other information (maybe even the parameter's name!).

- Introduce Subst trait, which helps to cleanup a lot of the
  repetitive code involved with doing type substitution.

- Introduce Repr trait, which makes debug printouts far more convenient.

Fixes #4183.  Needed for #5656.

d28f734412 Refactor so that references to traits are not represented using a type with a
bare function store (which is not in fact a kind of value) but rather
ty::TraitRef.  Removes many uses of fail!() and other telltale signs of
type-semantic mismatch.

6965fe4bce Add AbiSet and integrate it into the AST.
I believe this patch incorporates all expected syntax changes from extern
function reform (#3678). You can now write things like:

    extern "<abi>" fn foo(s: S) -> T { ... }
    extern "<abi>" mod { ... }
    extern "<abi>" fn(S) -> T

The ABI for foreign functions is taken from this syntax (rather than from an
annotation).  We support the full ABI specification I described on the mailing
list.  The correct ABI is chosen based on the target architecture.

Calls by pointer to C functions are not yet supported, and the Rust type of
crust fns is still *u8.

2a74fda316 Fix pretty-printer test failure by carrying the bound lifetime names through
the types.  Initially I thought it would be necessary to thread this data
through not only the AST but the types themselves, but then I remembered that
the pretty printer only cares about the AST.  Regardless, I have elected to
leave the changes to the types intact since they will eventually be needed.  I
left a few FIXMEs where it didn't seem worth finishing up since the code wasn't
crucial yet.

3ca7c225e5 Stop writing directly to the final type/method/vtable sidetables from astconv
and from typeck, which is verboten.  We are supposed to write inference results
into the FnCtxt and then these get copied over in writeback.  Add assertions
that no inference by-products are added to this table.

ca450e345f Move trans_enum_variant to trans::adt.
As a result, trans_enum_variant no longer cares what kind of enum it's
dealing with, so the "degen" parameter goes away in a bunch of places.

a30ea013f5 Handle supertrait calls in default methods
Add a new method_super origin for supertrait methods. Also make
coherence create a table that maps pairs of trait IDs and self types
to impl IDs, so that it's possible to check a supertrait method
knowing only its index in its trait's methods (without knowing all
supertraits for a given trait).

r=nmatsakis and graydon -- with hope, we'll revamp all of this code as
per #4678, but for now this fixes the bug.

Closes #3979
