18883fea3a In pre/postcondition computation, failing calls should set the postcondition 
A non-returning call should have a postcondition in which all predicates
are true -- not just a poststate. Otherwise, alt expressions where
one or more branches terminate in a non-returning call and others
initialize a variable get rejected.

Includes a test case.

9a24e4f780 Fix two typestate bugs 
* Non-returning calls should set all predicates to be true, not
  just the "this function returns" predicate

* Fixed a bug in the expr_alt case in tstate.states that wasn't updating
  the changed flag properly, then fixed *another* bug that was updating
  it too enthusiastically, but was masked by the first bug.

b6e0c5829f Check the declaration type in a for loop against the sequence type 
Changed the typechecker to correctly typecheck the declared variable
type in a for or for-each loop against the vector element type (for
a for loop) or the iterator type (for a for-each loop). Added a
test case.

e3b3a71e6a Don't fiddle with RUST_LOG in the Makefiles

0cbcf92749 Use annotations on blocks 
Previously, block_ty returned the type of the terminating
expression of the block (or nil if said expression was absent).
I changed check_expr to write the type of that expression into
the annotation for the block itself, so now block_ty can use the
block's annotation.

147b088125 Test for use of break as an expression 
The test was meant to verify that the typechecker correctly
allows a _|_ value (break, here) to be used in any context.
However, the compiler fails with an LLVM assertion failure.
I xfailed it, but wanted it to be on the record anyway.

1a96e79fe0 Make _|_ unify with anything 
The typechecker had a number of special cases for unifying types
with _|_ (as with checking if and alt). But, a value of type _|_
should be usable in any context, as such a value always diverges,
and will never be used by its immediate context. Changed unify
accordingly, removed special cases.
