8e00161819 Make the pretty printer disambiguatae blocks followed by vec expressions.
Semicolons are needed here now that postfix [] is used for vec indexing (the syntax change made in rev 518dc52f85).

b5f9053423 Add a constraint to trans::type_of
trans::type_of now has a constraint saying that its type argument
is statically sized. This eliminates the "impossible happened" case
in type_of. Yay!

I note that this change decreased translation time for stage2/rustc
from 16.1 s to 14.0 s. I also think many of the remaining checks
could be eliminated with some mildly clever use of constrained types
and further preconditions. Future work!

6ba4eacddf Make resolve recognize upvars
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

2d1dec78e7 Move mutability checking into its own pass.
Having it in the alias pass was slightly more efficient (finding
expression roots has to be done in both passes), but further muddled
up the already complex alias checker.

Also factors out some duplication in the mutability-checking code.

722fa00681 Get rid of the hack that ignores () typed things in fn tail position.
Closes #868. Unfortunately, this causes certain invalid programs to
fail type-checking instead of failing type-state when a type-state
error message would probably be more intuitive. (Although, by any
reasonable interpretation of the static semantics, it technically
ought to be a type error.)

7bbe8d2e8c Stop relying on klunky hack in alias.rs
It assumed node_ids increased monotonically for locals, but macros
make this no longer the case, and it was a dubious assumption anyway.

which.

e17e6af4f0 Change a number of result-returning functions to return @block_ctxt
The uniformity doesn't seem to be worth the extra noise and pointless
code being generated. If something doesn't produce a value, don't make
it return one. (For now, trans_[exprtype] things are left in the result-
returning form, even when they never return anything useful, since in
that case uniformity is arguably helpful.)

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.
