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.

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.

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.

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".

f39477d926 In resolve, check that an or-pattern has the same number of bindings in each disjunct
resolve3 wasn't checking this. Added test cases. Also added a helpful informational
message in the case where you have a variable binding that you probably think
refers to a variant that you forgot to import.

This is easier to do in resolve than in typeck because there's code in typeck
that assumes that each of the patterns binds the same number of variables.

697f1e38d6 Change 'native' and 'crust' to 'extern'.
This comes with a terminology change. All linkage-symbols are 'extern'
now, including rust syms in other crates. Some extern ABIs are
merely "foreign". The term "native" is retired, not clear/useful.

What was "crust" is now "extern" applied to a _definition_. This
is a bit of an overloading, but should be unambiguous: it means
that the definition should be made available to some non-rust ABI.
