- Checkin LARGE number of Changes to CEE pass that will make it much more
...
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.

Hoist the contents of Loops in depth first order in the dominator tree,
...
rather than in random order. This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before. This obviously
makes other transformations much more powerful as well!
