Lett users of sparse propagation do their own thing with phi nodes if they want
...
to. This can be combined with LCSSA or SSI form to store more information on a
PHINode than can be computed by looking at its incoming values.

This required converting a bunch of stuff off DOUT and other cleanups.

"This patch adds a virtual call to AbstractLatticeFunction to derive a
...
type lattice value for an Argument*, giving clients the opportunity to
use something other than Top for it if they choose to."

Add a new SparsePropagation analysis utility, which allows you to do
...
SCCP like sparse lattice analysis with relative ease. Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)
