25394950ae Handle the case where a child task tries to kill a parent while it is dying 
Still looks pretty racy

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.

b843cf2117 Generalize expression roots in alias analysis 
This allows calls-returning-a-reference to count as expression roots,
making it possible to return the result of such a call by reference.

propagating the failure (as if the child was reparented).

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.

be9fe24220 XFAIL some run-pass unwinding tests on win32 
Curiously, because of some unfortunate interaction between win32 hacks, all the
run-fail unwind tests actually pass (that wouldn't be the case if we were
valgrinding though).
