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).

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.

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.

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.

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).
