133d36f452 Require body of else-less if expressions to be a value-less block
For consistency with other constructs that could not possibly return a
value (say, loops).

66153436c9 Saner approach to lvalues and callable values in trans
LValues no longer carry information about generics and objs, instead
there's an extended form of lvalue, lval_maybe_callee, only used by
call and bind, which holds this info.

This makes it possible to take the value of a method and get a working
closure, and will (with some more work) allow us to call statically
known functions without loading from their pair.

Closes #435
Closes #758

f8a35234ad Remove autoderef for calls
We were only using it in a single place, and there for no discernable reason
(probably as part of the bare-fn-vals-are-not-copyable plan). It seems more
surprising than useful.

d7587c1eda Change convention for specifying referenced argument
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.

0b34e0e60b Introduce new semicolon rules
- Loop bodies and resource constructors aren't allowed to have
  trailing expressions anymore.

- An expression that ends* in a block without trailing expression can
  can not be called, indexed, or subscripted.

- Only expression-statements that end* in a block without trailing
  expression can omit their semicolon.

*) 'Ending in a trailing expression' is defined as being a block or
   construct-ending-in-a-block (if, alt) that either ends in an
   expression itself, or ends in another block-like expression that
   has a trailing expression (by these same rules).

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.

b5f9053423 Add a constraint to trans::type_of
trans::type_of now has a constraint saying that its type argument

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!

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.)

vec::zip now has the precondition that the two argument vectors
are the same length. Changed uses of it to reflect that.

Also added a few vector-enumerating utilities to vec.rs, which
necessitated in making some functions in u8 declared-pure.

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.
It now numbers locals itself and uses that to determine which precede
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.)

c9c5ee252a Implement non-internal ivecs
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.

Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.
