3c10a9412e remove unused functions, fix tiny lexing bug
before this change, the parser would parse 14.a() as a method call, but
would parse 14.ø() as the floating-point number 14. followed by a function
call. This is because it was checking is_alpha, rather than ident_start,
and was therefore wrong with respect to unicode.

2733a1f14b undo abstraction over whether to parse attrs in a block
In principle, it seems like a nice idea to abstract over the two
functions that parse blocks (one with inner attrs allowed, one not).
However, the existing one wound up making things more complex than
just having two separate functions, especially after the obsolete
syntax is (will be) removed.

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.

4ff701b7db auto merge of #5965 : alexcrichton/rust/issue-4364, r=pcwalton
This closes #4364. I came into rust after modes had begun to be phased out, so I'm not exactly sure what they all did. My strategy was basically to turn on the compilation warnings and then when everything compiles and passes all the tests it's all good.

In most cases, I just dropped the mode, but in others I converted things to use `&` pointers when otherwise a move would happen.

This depends on #5963. When running the tests, everything passed except for a few compile-fail tests. These tests leaked memory, causing the task to abort differently. By suppressing the ICE from #5963, no leaks happen and the tests all pass. I would have looked into where the leaks were coming from, but I wasn't sure where or how to debug them (I found `RUSTRT_TRACK_ALLOCATIONS`, but it wasn't all that useful).

ce4f73a243 auto merge of #5945 : graydon/rust/fix-unicode-tables, r=pcwalton
This switches the unicode functions in core to use static character-range tables and a binary search helper rather than open-coded switch statements. It adds about 50k of read only data to the libcore binary but cuts out a similar amount of compiled IR. Would have done it this way in the first place but we didn't have structured statics for a long time.

30dbbe17c9 auto merge of #5787 : alexcrichton/rust/less-mut-fields, r=catamorphism
This removes some of the easier instances of mutable fields where the explicit self can just become `&mut self` along with removing some unsafe blocks which aren't necessary any more now that purity is gone.

Most of #4568 is done, except for [one case](https://github.com/alexcrichton/rust/blob/less-mut-fields/src/libcore/vec.rs#L1754) where it looks like it has to do with it being a `const` vector. Removing the unsafe block yields:

```
/Users/alex/code/rust2/src/libcore/vec.rs:1755:12: 1755:16 error: illegal borrow unless pure: creating immutable alias to const vec content

```

I also didn't delve too much into removing mutable fields with `Cell` or `transmute` and friends.

5b933aeba2 auto merge of #5696 : thestinger/rust/hashmap, r=sanxiyn
This naming is free now that `oldmap` has finally been removed, so this is a search-and-replace to take advantage of that. It might as well be called `HashMap` instead of being named after the specific implementation, since there's only one.

SipHash distributes keys so well that I don't think there will ever be much need to use anything but a simple hash table with open addressing. If there *is* a better way to do it, it will probably be better in all cases and can just be the default implementation. 

A cuckoo-hashing implementation combining a weaker hash with SipHash could be useful, but that won't be as general purpose - you would need to write a separate fast hash function specialized for the type to really take advantage of it (like taking a page from libstdc++/libc++ and just using the integer value as the "hash"). I think a more specific naming for a truly alternative implementation like that would be fine, with the nice naming reserved for the general purpose container.

Changes the parser to parse all streams into token-trees before hitting the parser proper, in preparation for hygiene.  As an added bonus, it appears to speed up the parser (albeit by a totally imperceptible 1%).

Also, many comments in the parser.

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.

Hey folks,

This patch series does some work on the json decoder, specifically with auto decoding of enums. Previously, we would take this code:

```
enum A {
    B,
    C(~str, uint)
}
```

and would encode a value of this enum to either `["B", []]` or `["C", ["D", 123]]`. I've changed this to `"B"` or `["C", "D", 123]`. This matches the style of the O'Caml json library [json-wheel](http://mjambon.com/json-wheel.html). I've added tests to make sure all this work.

In order to make this change, I added passing a `&[&str]` vec to `Decode::emit_enum_variant` so the json decoder can convert the name of a variant into it's position. I also changed the impl of `Encodable` for `Option<T>` to have the right upper casing.

I also did some work on the parser, which allows for `fn foo<T: ::cmp::Eq>() { ... }` statements (#5572), fixed the pretty printer properly expanding `debug!("...")` expressions, and removed `ast::expr_vstore_fixed`, which doesn't appear to be used anymore.

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.
