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.

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.

4b566fe7f9 rustc: Hide the parser from syntax extensions 
Eventually extensions will probably need access to the parser again, but it'll
be in a different form.
