isolate predecessor computation
...
The new `Predecessors` type computes a set of interesting targets and
their HIR predecessors, and discards everything in between.

Use a BitVector instead of Vec<bool> for recording cleanup blocks
...
Also adds a FromIterator impl for BitVector to allow construction of a
BitVector from an iterator yeilding bools.

Add some standard traversal iterators for MIR
...
Adds Preorder, Postorder and Reverse Postorder traversal iterators.
Also makes trans/mir use Reverse Postorder traversal for blocks.

generalize bitvector code into a bitmatrix; write some unit tests, but
...
probably not enough. This code is so simple, what could possibly go
wrong?

Use vec![elt; n] where possible
...
The common pattern `iter::repeat(elt).take(n).collect::<Vec<_>>()` is
exactly equivalent to `vec![elt; n]`, do this replacement in the whole
tree.
(Actually, vec![] is smart enough to only call clone n - 1 times, while
the former solution would call clone n times, and this fact is
virtually irrelevant in practice.)

Port to using the newer graph, which offers iterators instead of the
...
older `each` method, but is otherwise identical.
