8cbdaf4f93 Make trans use span_err for the dreaded "ty_var in trans::type_of" error 
This required quite a bit of tiresome plumbing about of spans.
On the bright side, now other errors can be converted to span_err too.

Includes test cases.

a98ea4f3ef rustc: Run block cleanups on else if blocks 
With the scheme used to translate 'else if' currently the if expression is
translated in a new (else) scope context. If that if expression wants to
result in a value that requires refcounting then it will need to drop the
refcount in the cleanups of the else block.

fbfd8552ab Return a better result from blocks. Closes issue #377 
Blocks return in a copy of the result of their ending expression, not the
direct result of the ending expression, as that may be a local variable which
gets zeroed by drop_slot.

387a8888ee Fix get_os and get_arch

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.)

2b36e40c58 Ensure ann tags are actually kept around during typechecking

what ld.so does, so gdb is happy and stops a backtrace at rust_exit_task_glue

rust_exit_task_glue is the object file.

This is only the rustc changes and should be merged first.

have a boolean return type and can only call other preds; they
can't have any effects (as enforced by the typechecker).
The arguments to a predicate in a check expression must be
slot variables or literals.

34dae82b48 Add a session field to ty_ctxt and change an err to span_err 
I changed instantiate to print out a more helpful error message,
which required passing it a session argument. To avoid
threading extra arguments through a lot of functions,
I added a session field to ty_ctxt.

844fe20720 Fix some nested patterns in rustc 
In rustc, nested patterns were potentially matching when they shouldn't
match, because a loop index wasn't being incremented. Fixed it and added
one test case.

707cd0281d Fixed bug in typeck that wasn't filling in anns for stmts 
(needed for typestate_check).

Also changed a (log; fail) to (log_err; fail) in typestate_check,
and added some more logging funs in util.common.

0190ebfe07 Support all expression forms in typestate 
Added support for self_method, cont, chan, port, recv, send, be,
do_while, spawn, and ext; handled break and cont correctly.
(However, there are no non-xfailed test cases for ext or spawn in
stage0 currently.)

Although the standard library compiles and all test cases pass with
typestate enabled, I left typestate checking disabled as rustc
terminates abnormally when building the standard library if so,
even though it does generate code correctly.

7c4f8cb459 Further work on typestate_check 
Lots of work on typestate_check, seems to get a lot of the way
through checking the standard library.

* Added for, for_each, assign_op, bind, cast, put, check, break,
and cont. (I'm not sure break and cont are actually handled correctly.)

* Fixed side-effect bug in seq_preconds so that unioning the
preconditions of a sequence of statements or expressions
is handled correctly.

* Pass poststate correctly through a stmt_decl.

* Handle expr_ret and expr_fail properly (after execution of a ret
or fail, everything is true -- this is needed to handle ifs and alts
where one branch is a ret or fail)

* Fixed bug in set_prestate_ann where a thing that needed to be
mutated wasn't getting passed as an alias

* Fixed bug in how expr_alt was treated (zero is not the identity
for intersect, who knew, right?)

* Update logging to reflect log_err vs. log

* Fixed find_locals so as to return all local decls and exclude
function arguments.

* Make union_postconds work on an empty vector (needed to handle
empty blocks correctly)

* Added _vec.cat_options, which takes a list of option[T] to a list
of T, ignoring any Nones

* Added two test cases.
