4e136d1fd9 Add rustc::middle::cstrcache for getting c string bufs safely 
We continue to leak string buffers in trans so this creates a way to get c
string buffers from strings while guaranteeing that they are not freed before
use.

Hopefully this can be made efficient in the istr regime.

5917d80cd7 Pass stuff to take_ty, free_ty, and drop_ty by address, even when immediate 
The glue-calling will spill the values again anyway. This should
prevent a lot of load/spill junk in the output. It is also necessary
to be able to have unique vecs be immediate values (take must know the
actual address to be able to duplicate).

1b60bba141 Use typestate constraints for trans_be 
trans_be now has a precondition that its expression argument
is a call expr. Obviously this code may be going away soon, but
I wanted to exercise typestate somehow and this was an easy one :-)

f841e89443 Support unchecked blocks 
This patch supports the syntax

    unchecked {
      ...
    }

    to disable purity checking within a block. Presumably it will only be
    used within a declared "pure fn". However, there is no checking that it
    doesn't occur elsewhere, and it would be harmless for it to do so.

    I went with Lindsey's suggestion for the syntax, but it's subject to
    change.

    This allows you to write code that uses predicates that call arbitrary
    Rust functions, but you must declare your intentions by wrapping it in
    an unchecked { ... } block. The test case run-pass/unchecked-predicates.rs
    demonstrates how to do that.

c6155d1fd1 Change "pred" to "pure fn" (but still accept "pred") 
This is part 1 of changing the "pred" keyword to "pure fn".
Right now, the compiler accepts both "pred" and "pure fn".

b9112525ba Move to a more lightweight builder system 
You now do

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

e58c48bdda Optimize += [x] into a simple push operation 
This is a preparation for making vectors always-on-the-heap again,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

b24f978011 Drop arguments on the caller side, not the callee

35c962e9a1 Pass structural types by pointer, not by value 
If we lose tail calls, this is possible. It simplifies things a lot.

Direct motivation: We want ivecs with pointers pointing into
themselves. When copying those, the pointers have to be adjusted. It
is impossible to this when copying them with Load/Store.

0a8bffceb3 Simplify the _rust_main/rust_start interface 
rust_start will always call _rust_main with the command line args, and it is
_rust_main's responsibility to free the args ivec heap. _rust_main will be
generated slightly differently depending on whether main takes an ivec or not:
if so then it's just passed through to main, otherwise it frees the ivec
directly.

0340f32748 Eliminate autoderef on binops and unary negation. 
Autoderef on binops is basically unused, kind of silly, and
complicates typechecking. There were only three instances of it in the
compiler and the test drivers, two of which were of the form "*foo =
foo + 1", which should be written as "*foo += 1" anyways.

c5c8258937 Rework check_expr substantially. 
The bulk of check_expr is now check_expr_with_unifier, which takes an
expected type and a unification function and will perform the
unification on the type it produces. check_expr calls
check_expr_with_unifier with a dummy unifier and a new function,
check_expr_with, takes an expected type and uses the simple unifier.

I think this generally makes thing cleaner, but the purpose for doing
this is to enable type inferred lambda-blocks to be useful by allowing
the argument types to be unified before the body of the lambda is
checked.

1c786bcc82 Initialize all constraints to False 
Previously, typestate was initializing the init constraint for
a declared-but-not-initialized variable (like x in "let x;") to False,
but other constraints to Don't-know. This led to over-lenient results
when a variable was used before declaration (see the included test
case). Now, everything gets initialized to False in the prestate/poststate-
finding phase, and Don't-know should only be used in pre/postconditions.

This aspect of the algorithm really needs formalization (just on paper),
but for now, this closes #700

d7ee55bfd0 (Almost) Always unify a function tail expr with the function result type 
typeck::check_fn had an exception for the case where the tail expr
was compatible with type nil -- in that case, it doesn't unify the
tail expr's type with the enclosing function's result type. This
seems wrong to me. There are several test cases in Issue #719
that illustrate why. If the tail expr has type T, for some type
variable T that isn't resolved when this check happens, then T
never gets unified with anything, which is incorrect -- T should
be unified with the result type of the enclosing function. (The
bug was occurring because an unconstrained type variable is
compatible with type nil.)

Instead, I removed the check for type nil and added a check that
the function isn't an iterator -- if it's an iterator, I don't
check the tail expr's type against the function result type,
as that wouldn't make sense.

However, this broke two test cases, and after discussion with
brson, I understood that the purpose of the check was to allow
semicolons to be omitted in some cases. The whole thing seems
rather ad hoc. But I came up with a hacky compromise solution:
instead of checking whether the tailexpr type is *compatible*
with nil, we now just check whether it *is* nil. This also
necessitates calling resolve_type_vars_if_possible before
the check happens, which worries me. But, this fixes the bug
from Issue #719 without requiring changes to any test cases.

Closes #719 but I didn't try every variation -- so reopen the bug
if one of the variations still doesn't work.

2baaeab784 Implement the occurs check 
In the writeback phase, the typechecker now checks that it isn't
replacing a type variable T with a type that contains T. It
also does an occurs check in do_autoderef in order to avoid
getting into an infinite chain of derefs.

I'm a bit worried that there are more places where the occurs
check needs to happen where I'm not doing it now, though.
