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 :-)

e5eacf8ea9 Use RHS type when translating assignments 
In code like "auto foo = fail", a type gets inferred for foo
depending on how it's used. However, fail still has type _|_ and
still should be treated that way: particularly, its value shouldn't
be copied. Fixed trans to reflect that.

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.

537d879dc1 Properly handle lifetime of aliases in nested blocks 
There was a bug that would cause the alias analyser to allow you to
invalidate an alias that was no longer directly referred to, even if
another alias was rooted in it. It now properly tracks dependencies
between live aliases.

Required another case of copying values in map.rs.

beda82ddf1 A revised, improved alias-checker 
The old system tried to ensure that the location an alias pointed at
would retain its type. That turned out to not be strong enough in the
face of aliases to the inside of tags.

The new system instead proves that values pointed to by aliases are
not replaced (or invalidated in some other way) at all. It knows of
two sufficient conditions for this, and tries to prove at least of
them:

A) The alias is 'immutably rooted' in a local, and this local is not
   reassigned for the lifetime of the alias. Immutably rooted means
   the alias refers to the local itself, or to something reachable
   from the local through immutable dereferencing.

B) No value whose type might include the type of the 'inner mutable
   element' of the thing the alias refers to (for example, the box in
   rec(mutable x = @mutable int)) is from the outer scope is accessed
   for the lifetime of the alias. This means for functions, no other
   argument types may include the alias's inner mutable type. For alt,
   for each, and for, it means the body does not refer to any locals
   originating from outside their scope that include this type.

The lifetime of an alias in an alt, for each, or for body is defined
as the range from its definition to its last use, not to the point
where it goes out of scope. This makes working around these
restrictions somewhat less annoying. For example, you can assign to
your alt-ed value you don't refer to any bindings afterwards.

77c1b9650f Some more workarounds to please the alias checker 
Some of the vec utilities now only work on immutable vecs, since they
would have to be rewritten to do a lot more copying to be alias-safe.

Some forced copying was added to map.rs, showing a weakness in the
alias checker (or maybe the alias system): when fn args are passed
into a function, calling them must assume all aliases that are not
immutably rooted (directly connected to a local or temporary without
any mutable edges) become invalid. This will be a drag on functional
programming in Rust.

Work around alias issues in the stdlib

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.

2b334f061a Change unsafe aliases 
This litters aberrations like 'alt({foo.bar}) { ... }' and f({*baz})
though the code (mostly in trans.rs). These are a way to explicitly
copy the given value so that it can be safely aliased. At some point
we'll probably want a more explicit copy operator.

18b63865ce Accept *foo as a pointer to foo. 
This is accepted everywhere, since just passing a pointer is safe.

468786e36d Fix unification bug 
Hello from SFO Terminal 3!

unify_fn_common had the expected and actual types reversed in one
place. This was causing the type of an occurence of a function f
with type fn(int) -> T to be set to fn(_|_) -> T at a call site like
f(fail); I think this was also making some of the type error messages
come out backwards, but I haven't checked.

Also: ty_bot does not contain pointers
