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.

97452c0ca1 Remove modes from map API and replace with regions.
API is (for now) mostly by value, there are options to use it by
reference if you like.  Hash and equality functions must be pure
and by reference (forward looking to the day when something
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.

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
is expensive to copy, and it will warn you if you use any explicit
mode other than copy.  So you should migrate over to using the
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.

07a81ad12e Refactor how impl self types are stored
In order to avoid a confusing use of the tcache, I added an extra

in the tcache to get the self type).

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).

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.

91e44ea056 Be a little more clever about calculating sizes for class types
We could try to calculate the size of a partially-converted class type,
and run into an LLVM error because we were trying to calculate the size
of a named struct whose fields hadn't yet be filled in. The issue can be
dodged by extending simplify_type to convert classes to isomorphic
structural records, just for the purposes of size calculations.

093faaabe1 Handle index expressions' callee IDs correctly
Some code that handles unary and binary exprs' callee IDs was
    forgetting to handle the index expr case (since calls to
    user-defined index operators also have callee IDs). This was
    manifesting as an ICE in trans because when monomorphizing a
    function that had one of these operators in it (an index into a
    dvec, in the test case), the callee ID would be unbound to a type.

    Fixed it. Closes #2631.

77e6573929 Further work on integer literal suffix inference (#1425)
In this commit:

  * Change the lit_int_unsuffixed AST node to not carry a type, since
    it doesn't need one

  * Don't print "(unsuffixed)" when pretty-printing unsuffixed integer
    literals

  * Just print "I" instead of "(integral)" for integral type variables

  * Set up trans to use the information that will be gathered during
    typeck to construct the appropriate constants for unsuffixed int
    literals

  * Add logic for handling int_ty_sets in typeck::infer

  * Clean up unnecessary code in typeck::infer

  * Add missing mk_ functions to middle::ty

  * Add ty_var_integral to a few of the type utility functions it was
    missing from in middle::ty

97bcb20244 Avoid some duplicated typechecking work
There was a FIXME noting that ty::enum_variants and typeck::check::
check_enum_variants both call eval_const_expr. I tried refactoring the
code so that check_enum_variants does all the work and enum_variants
just looks up cached results, but this turned out not to be easy because
several ty functions call enum_variants and it might get invoked on an
enum before that enum item has been typechecked. Instead, I just made
check_enum_variants update the enum_var_cache so that enum_variants
will never call eval_const_expr twice on the same const.

6f95c79b95 Traverse types in reachability
Issue 2526 showed a test case where a library exported only a type
that was a synonym for a class. Because the class's destructor wasn't
getting marked as reachable, its linkage was wrongly getting set to
"internal". The solution is for reachability to traverse types.

Closes #2526.

72360970fc Change trans::common::block to be a class
And replace trans::common::block_parent with option<block>. To handle
the recursive self-reference in the block_ class, I had to add a
newtype-like enum "block" which is equivalent to @block_ -- which due
to an interaction with borrowck, resulted in having to change a few
functions in trans::base to take their block argument in ++ mode,
irritatingly enough (but not that irritatingly, since we're supposed to
get rid of modes).
