ddec6b5f47 rustc: Use a set-based approach to unification; remove ty_bound_param and ty_local.
Sorry, big perf regression; will fix soon.

b1d6f12a05 Don't put a copy of main (the C one) in each binary we produce. This is a step
in getting a driver that works on all linux systems.

Sorry for the linker hacks, I will remove them after snapshotting a new compiler.

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.

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.

Introduce an ext_ctxt record to provide a span_err method for use while

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
