6fe59bf877 Add a field borrow_offset to the type descriptor indicating
what amount a T* pointer must be adjusted to reach the contents
of the box. For `~T` types, this requires knowing the type `T`,
which is not known in the case of objects.

63c62bea3a auto merge of #8420 : blake2-ppc/rust/shrink-token, r=cmr
`enum Token` was 192 bytes (64-bit), as pointed out by pnkfelix; the only
bloating variant being `INTERPOLATED(nonterminal)`.

Updating `enum nonterminal` to use ~ where variants included big types,
shrunk size_of(Token) to 32 bytes (64-bit).

I am unsure if the `nt_ident` variant should have an indirection, with
ast::ident being only 16 bytes (64-bit), but without this, enum Token
would be 40 bytes.

A dumb benchmark says that compilation time is unchanged, while peak
memory usage for compiling std.rs is down 3%

f08851e31a auto merge of #8421 : alexcrichton/rust/unnamed-addr, r=thestinger
This can be applied to statics and it will indicate that LLVM will attempt to
merge the constant in .data with other statics.

I have preliminarily applied this to all of the statics generated by the new
`ifmt!` syntax extension. I compiled a file with 1000 calls to `ifmt!` and a
separate file with 1000 calls to `fmt!` to compare the sizes, and the results
were:

```
fmt           310k
ifmt (before) 529k
ifmt (after)  202k
```

This now means that ifmt! is both faster and smaller than fmt!, yay!

8b9e1ce75a auto merge of #8430 : erickt/rust/cleanup-iterators, r=erickt
This PR does a bunch of cleaning up of various APIs. The major one is that it merges `Iterator` and `IteratorUtil`, and renames functions like `transform` into `map`. I also merged `DoubleEndedIterator` and `DoubleEndedIteratorUtil`, as well as I renamed various .consume* functions to .move_iter(). This helps to implement part of #7887.

2ba36ec629 auto merge of #8327 : sstewartgallus/rust/factor_out_waitqueue, r=bblum
I'm a bit disappointed that I couldn't figure out how to factor out more of the code implementing `extra::sync` but I feel this is an okay start. Also I added some documentation explaining that `WaitQueue` isn't thread safe, and needs an exclusive lock.

e70aac572a auto merge of #8270 : dotdash/rust/ret_alloca_elim, r=pcwalton
When there is only a single store to the ret slot that dominates the
load that gets the value for the "ret" instruction, we can elide the
ret slot and directly return the operand of the dominating store
instruction. This is the same thing that clang does, except for a
special case that doesn't seem to affect us.
