powerful, but that are largely disabled. The basic idea here is that it
is trying to forward branches across basic blocks that have PHI nodes in
it, which are crucial to be able to handle cases like whet.ll.
Unfortunately we are not updating SSA correctly, causing sim.c to die, and I
don't have time to fix the regression now, so I must disable the
functionality.

Fix a nasty problem with dominance calculation for unreachable blocks.

apparently dominate "unreachable". This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
