Several major fixes, particularly in emitting constant aggregates:
...
(1) Padding bytes between structure fields (for alignment) were never
being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
were never handled.
(3) Support new model for external/uninitialized/initialized globals.
Uninitialized globals are no longer emitted since they are external.
Initialized globals may go either in .bss or in .data.

- 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.

Fix a nasty problem with dominance calculation for unreachable blocks.
...
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable". This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
