f3b2296ee4 Auto-deref the base expr in trans_method_callee 
(specifically in the method_trait case) -- if you wrote x.f()
and x has type @T for a trait T, x wasn't getting auto-deref'ed.

This was bad.

a6a5c48c64 make ref x bindings produce region ptrs and fix various minor bugs 
we now detect inconsistent modes, binding names, and various other errors.
typeck/trans integration is mostly done.

borrowck not so much.

more tests needed.

948172b93f Make comparisons between region pointers work 
Region pointers were considered a scalar type, so compare_scalar_type would
get called to compare region pointers in trans. This would fail, since
compare_scalar_type has no case for region pointers.

Changed type_is_scalar to return false for region pointers. This had the side
effect of breaking casts to types of the form &T. To ameliorate that, I added
library functions ptr::assimilate (taking a &T to a *T) and ptr::to_uint
(taking a &T to a uint), both of which use reinterpret_cast.

While I was at it, I removed ty::type_has_resources, which is dead code.

c2bb2f0837 When checking loop bodies and do-expr bodies, don't require the expected type to exist 
If the expected type is none (due to a type error), we shouldn't fail with an ICE, but
rather, just print out another type error. Changed the do-expr type error message to
make sense in this context (see the test case for how it works).

Closes #3044.

like send_map becomes the standard map).

5d32d03b89 Fix #2979: inference for lifetimes of & expressions 
What we now do is to create a region variable for each &
expression (and also each borrow).  The lifetime of this
variable will be checked by borrowck to ensure it is not greater
than the lifetime of the underlying data.  This both leads to
shorter lifetimes in some cases but also longer in others,
such as taking the address to the interior of unique boxes
tht are rooted in region pointers (e.g., returning a pointer
to the interior of a sendable map).

This may lead to issue #2977 if the rvalue is not POD, because
we may drop the data in trans sooner than borrowck expects us
to.  Need to work out precisely where that fix ought to occur.

1854a736f8 rustc: use new siphash impl instead of sha1 
Updating types std::sha1::sha1 -> hash::streaming was a relatively
    small change.  Renaming the variables to reflect that things aren't
    sha1s any more touched far more lines.

082d8314da Rewrite bitv to use classes and optimize its representation 
Rewrote bitv as a class that uses a 32-bit int as its representation
for bit vectors of 32 bits or less, and a vector (the old representation)
otherwise. I didn't benchmark very much, but a bit of informal benchmarking
suggested this is a win.

a0d05844ed Correctly forbid upvars in nested impls, traits and classes 
Previously, resolve was allowing impls, traits or classes that were
nested within a fn to refer to upvars, as well as referring to type
parameters bound by the fn. Fixing this required adding a new kind of
def: def_typaram_binder, which can refer to any of an impl, trait or
class that has bound ty params. resolve uses this to enforce that
methods can refer to their parent item's type parameters, but not to
outer items' type parameters; other stages ignore it. I also made
sure that impl, trait and class methods get checked inside a
MethodRibKind thing so as to forbid upvars, and changed the definition
of MethodRibKind so that its second argument is an optional node_id
(so that required trait method signatures can be checked with a
MethodRibKind as well).

dbbaa50290 Nomenclature fixes in the lint checker. Fewer double-negatives. 
New style is allow(foo), warn(foo), deny(foo) and forbid(foo),
mirrored by -A foo, -W foo, -D foo and -F foo on command line.

These replace -W no-foo, -W foo, -W err-foo, respectively.

Forbid is new, and means "deny, and you can't override it".

It will warn you if you use the default mode for something that

default mode for most things (and borrowed pointers when you don't
want to copy) and copy mode for things you really wanted to copy.

5a63b2100e More consistent use of backticks and "expected" in error messages. 
Got some of the debug messages, here, too.  I figure it doesn't hurt
to get used to doing this even in places where users won't ever see
it.

07a81ad12e Refactor how impl self types are stored 
In order to avoid a confusing use of the tcache, I added an extra
node ID field to trait refs. Now trait refs have a "ref ID" (the one
that resolve3 resolves) and an "impl ID" (the one that you look up
in the tcache to get the self type).

Closes #2434

78ec6fe30c Obliterate the callee_id hack 
Exprs that could be applications of overloaded operators
(expr_unary, expr_binary, expr_index) relied on the previous node ID
being "reserved" to carry extra typechecking info. This was
incredibly error-prone. Fixed it; now all exprs have two node IDs
(which will be wasted in some cases; future work could make this
an option instead if the extra int field ends up being a performance
problem).

Closes #2804

aba665da32 Fix the signature on vec::view. 
Due to limitations in region inference, this has the effect of making vec::view pretty much entirely unusable.
