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).
