9f1444c701 Implement "claim"
Implement "claim" (issue #14), which is a version of "check" that
doesn't really do the check at runtime. It's an unsafe feature.

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.

61fc12d0d0 Partial implementation of resources
Non-copyability is not enforced yet, and something is still flaky with
dropping of the internal value, so don't actually use them yet. I'm
merging this in so that I don't have to keep merging against new
patches.

05c0216654 rustc: Add ternary operator. Closes #565
The implementation is so simple it might be considered cheating: at almost
every step the expr_ternary is just converted to expr_if.

84005fadbf Some progress on support for extending objects with new fields (issue
into four separate issues (#538, #539, #540, #543) with corresponding
tests.

c34e9b33d9 Move expr ids into the expr record type
This simplifies the tag variants a bit and makes expr_node_id
obsolete.

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.

219924e669 Bring back if-check
Add "if check" (expr_if_check), a variation on check that executes
an "else" clause rather than failing if the check doesn't hold.

15f71b3600 Refactor ast::item representation
Most of the fields in an AST item were present in all variants. Things
could be simplified considerably by putting them in the rec rather
than in the variant tags.

471436a299 Implement function expressions/anonymous functions
Looks like 'fn(..arg..) -> ret {body;}. They don't support type
parameters or upvars yet.

d65ad8c31c Change decl to local in expr_for and expr_for_each
Since the decl in a for or for-each loop must always be a local
decl, I changed the AST to express this. Fewer potential match
failures and "the impossible happened" error messages = yay!

698c6406ba Reject programs with unsatisfied predicate constraints
Generate appropriate constraints for calls to functions with
preconditions, and reject calls where those constraints don't
hold true in the prestate.

...by which I mean that it works for one test case :-)

17ff2a0d79 Further support for predicate constraints
Changed function types to include a list of constraints. Added
code for parsing and pretty-printing constraints. This necessitated
splitting pprust into two files (pprust and ppaux) to break a
circulate dependency, as ty_to_str now needs to print out constraints,
which may include literals, but pprust depended on ty.
