2aac43d809 Simplify trans::new_fn_ctxt_w_id 
It was still living in the pre-decent-type-inference era.

63519d9006 Rename restrict to binding in alias.rs 
Its role gradually changed to the point where the old name doesn't
really make sense anymore.

6d3dd0e48c Try harder still to generate fewer landing pads 
Scopes that don't have cleanups don't need their own landing pads

This takes the optimized rustc bin from 4.7MB to 4.4

b8e31ac469 Try a little harder to avoid creating new landing pads 
It's only when we add or revoke cleanups involving immediates that we need a
new landing pad for the scope.

Trims 5K off the optimized rustc bin

be5537e95f Be more strict about what constitutes a block expression 
Blocks (or statements involving blocks) that end in a semicolon are no
longer considered the block-expression of their outer block. This used
to be an expression block, but now is a statement block:

    { if foo { ret 1; } else { ret 10; } }

This helps clear up some ambiguities in our grammar.

signatures. See [1].

c047cfb710 Unwind the stack on task failure

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!

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

is a call expr. Obviously this code may be going away soon, but

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.
