8d0feb58e7 auto merge of #7763 : dotdash/rust/empty_blocks, r=pcwalton
These commits remove a bunch of empty or otherwise unnecessary blocks, reducing the size of the pre-optimization IR and improving its readability. `librustc.ll` created with `--passes ""` shrinks by about 120k lines which equals about 5% of the total size.

e56b3691c8 Use concrete types in glue functions
We used to have concrete types in glue functions, but the way we used
to implement that broke inlining of those functions. To fix that, we
converted all glue to just take an i8* and always casted to that type.

The problem with the old implementation was that we made a wrong
assumption about the glue functions, taking it for granted that they
always take an i8*, because that's the function type expected by the
TyDesc fields. Therefore, we always ended up with some kind of cast.

But actually, we can initially have the glue with concrete types and
only cast the functions to the generic type once we actually emit the
TyDesc data.

That means that for glue calls that can be statically resolved, we don't
need any casts, unless the glue uses a simplified type. In that case we
cast the argument. And for glue calls that are resolved at runtime, we
cast the argument to i8*, because that's what the glue function in the
TyDesc expects.

Since most of out glue calls are static, this saves a lot of bitcasts.
The size of the unoptimized librustc.ll goes down by 240k lines.

403cdd84a4 auto merge of #7765 : blake2-ppc/rust/ord-default-methods, r=huonw
Rust will allow to supply default methods for all four methods, but we
don't have any nice error reporting for the case where at least one
method must be implemented, but it's arbitrary which.

So in this case, we require `lt`, but allow implementing the others if needed.

dcd5d14e6c Avoid return blocks that have only a single predecessor
Currently, we always create a dedicated "return" basic block, but when
there's only a single predecessor for that block, it can be merged with
that predecessor. We can achieve that merge by only creating the return
block on demand, avoiding its creation when its not required.

Reduces the pre-optimization size of librustc.ll created with --passes ""
by about 90k lines which equals about 4%.

36f20423c3 cmp: Use default methods in trait Ord, only require Ord::lt
It will be simpler to implement only one method for Ord, while we also
allow implementing all four Ord methods for semantics or performance
reasons.

We only supply three default methods (and not four), because don't have
any nice error reporting for the case where at least one method must be
implemented, but it's arbitrary which.

c095a5c6cb dlist: Use a DoubleEndedIterator for .mut_iter() and .mut_rev_iter()
Unify the mutable iterators too. Switch the ListInsertion trait to use
method .insert_next() and .peek_next() for list mutation. .insert_next()
inserts an element into the list that will not appear in iteration, of
course; so the length of the iteration can not change during iteration.

When it's a lifetime, a single quotation mark shouldn't have a matching
single quotation mark inserted after it, as delimitMate does by default.

Note that this is not without problems; a char literal coming after an
odd number of lifetime markers will have its quotation marks behave a
little strangely. That, however, is not my fault, but delimitMate's:

917d720f48 rustc compiler config for Vim.
Note that this is not actually *used* by default; it is a matter of
configuration still, because you might want to:

- Compile all .rs files with `rustc %` (where each can be built itself)

- Compile all .rs files with `rustc some-file.rs` (where you are editing
  part of a crate)

- Compile with a different tool, such as `make`. (In this case you might
  put a `~/.vim/after/compiler/rustc.vim` to match such cases, set
  makeprg and extend errorformat as appropriate. That should probably go
  in a different compiler mode, e.g. make-rustc.)

To try using it, `:compiler rustc`. Then, `:make` on a file you would
run `rustc` on will work its magic, invoking rustc. To automate this,
you could have something like `autocmd FileType rust compiler rustc` in
your Vim config.

07183ea6e7 auto merge of #7677 : alexcrichton/rust/tls-gc, r=pcwalton
cc #6004 and #3273

This is a rewrite of TLS to get towards not requiring `@` when using task local storage. Most of the rewrite is straightforward, although there are two caveats:

1. Changing `local_set` to not require `@` is blocked on #7673
2. The code in `local_pop` is some of the most unsafe code I've written. A second set of eyes should definitely scrutinize it...

The public-facing interface currently hasn't changed, although it will have to change because `local_data::get` cannot return `Option<T>`, nor can it return `Option<&T>` (the lifetime isn't known). This will have to be changed to be given a closure which yield `&T` (or as an Option). I didn't do this part of the api rewrite in this pull request as I figured that it could wait until when `@` is fully removed.

This also doesn't deal with the issue of using something other than functions as keys, but I'm looking into using static slices (as mentioned in the issues).

This patch is a step towards #6298. It extracts the graph abstraction from region inference into a library, and then ports the region inference to use it. It also adds a control-flow graph abstraction that will eventually be used by dataflow. The CFG code is not yet used, but I figured better to add it so as to make later rebasing etc easier.
