0148daa058 Reorganize structure of build directory 
Each stage is organized more according to Unix standards and to
accommodate multiple target architectures.

stageN/
  bin - rustc lives here
  lib - libraries that rustc needs

4be7e1e5cd Pass all arguments by reference, make immut alias mode equiv to value 
Arguments that can't be safely referenced will be implicitly copied.

(Warnings for expensive copies will be forthcoming.)

This will allow us to get rid of most of the ampersands in function
signatures. See [1].

6ba4eacddf Make resolve recognize upvars 
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

2d1dec78e7 Move mutability checking into its own pass. 
Having it in the alias pass was slightly more efficient (finding
expression roots has to be done in both passes), but further muddled
up the already complex alias checker.

Also factors out some duplication in the mutability-checking code.

bd4aeef78b Beginnings of support for constrained types 
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

6fd6fdea93 Move everything syntax-related to syntax/, break deps on rest of compiler 
src/comp/syntax is currently just a sub-module of rustc, but it will,
in the near future, be its own crate. This includes:

 - The AST data structure
 - The parser
 - The pretty-printer
 - Visit, walk, and fold
 - The syntax extension system
 - Some utility stuff that should be in the stdlib*

*) Stdlib extensions currently require a snapshot before they can be
   used, and the win build is very broken right now. This is temporary
   and will be cleaned up when one of those problems goes away.

A lot of code was moved by this patch, mostly towards a more organized
layout. Some package paths did get longer, and I guess the new layout
will take some getting used to. Sorry about that!

Please try not to re-introduce any dependencies in syntax/ on any of
the other src/comp/ subdirs.

4165d3640a Add a pass to fold out items that do not belong in the current configuration 
The parser needs to parse unconfigured items into the AST so that they can
make the round trip back through the pretty printer, but subsequent passes
shouldn't care about items not being translated. Running a fold pass after
parsing is the lowest-impact way to make this work. The performance seems
fine.

190644063e Be more strategic about linking to rust crates 
Instead of linking directly to the rust crate, try to figure out the location
and name of the library from the file name, then call gcc with appropriate -L,
-l flags. This will allow dynamic linking to be more forgiving about where it
loads the library from at runtime - currently a stage3 compiler can't run
correctly from the stage0 directory. Only tested on Linux. Fingers crossed.

9f1444c701 Implement "claim" 
Implement "claim" (issue #14), which is a version of "check" that

The new flag --check-claims turns claims into checks automatically --
but it's off by default, so by default, the assertion in a claim
doesn't execute at runtime.

75681f9ad7 Get rid of def_ids and anns in AST nodes, use single node_id 
This reduces some redundancy in the AST data structures and cruft in
the code that works with them. To get a def_id from a node_id, apply
ast::local_def, which adds the local crate_num to the given node_id.
Most code only deals with crate-local node_ids, and won't have to
create def_ids at all.

a5bca7df88 Refactor data structures representing constraints (again...) 
I added a "resolved" version of the ast::constr type -- ty::constr_def
-- that has a def_id field instead of an ann_field. This is more
consistent with other types and eliminates some checking.

Incidentally, I removed the def_map argument to the top-level function
in middle::alias, since the ty::ctxt already has a def_map field.

Changed function types to include a list of constraints. Added

which may include literals, but pprust depended on ty.

4bd5f834b0 First take on an alias-safety checker 
The alias checker works by ensuring that any value to which an alias
is created is rooted in some way that ensures it outlives the alias.

It is now disallowed to create an alias to the content of a mutable
box, or to a box hanging off a mutable field. There is also machinery
in place to prevent assignment to local variables whenever they are
the root of a live alias.

971b5d5151 Started adding support for return checking and non-returning function annotations 
* Reorganized typestate into several modules.

* Made typestate check that any function with a non-nil return type
  returns a value. For now, the check is a warning and not an error
  (see next item).

* Added a "bot" type (prettyprinted as _|_), for constructs like be, ret, break, cont, and
  fail that don't locally return a value that can be inspected. "bot"
  is distinct from "nil". There is no concrete syntax for _|_, while
  the concrete syntax for the nil type is ().

* Added support to the parser for a ! annotation on functions whose
  result type is _|_. Such a function is required to have either a
  fail or a call to another ! function that is reached in all control
  flow paths. The point of this annotation is to mark functions like
  unimpl() and span_err(), so that an alt with a call to err() in one
  case isn't a false positive for the return-value checker. I haven't
  actually annotated anything with it yet.

* Random bugfixes:

* * Fixed bug in trans::trans_binary that was throwing away the
    cleanups for nested subexpressions of an and or or
    (tests: box-inside-if and box-inside-if2).

** In typeck, unify the expected type arguments of a tag with the
   actual specified arguments.

358a1aeec9 Keep resolve data in external hash table, rather than embedded defs 
One step closer to removing fold and having a single, immutable AST.
Resolve still uses fold, because it has to detect and transform
expr_field expressions. If we go through on our plan of moving to a
different syntax for module dereferencing, the parser can spit out
expr_field expressions, and resolve can move to walk.

(I am truly sorry for the things I did in typestate_check.rs. I expect
we'll want to change that to walk as well in the near future, at which
point it should probably pass around a context record, which could
hold the def_map.)
