e1c09309f2 Add a call to 'write' right before the call to abort() in the unwind path. 
This causes the JIT, or LLC'd program to print out a nice message, explaining
WHY the program aborted.

c3f5f7701f Instead of callign removeTriviallyDeadNodes on the global graph every time 
removeDeadNodes is called, only call it at the end of the pass being run.
This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is
pretty big.  This is only possible because of the automatic garbage
collection done on forwarding nodes.

4ff0b9636d Substantially improve the DSA code by removing 'forwarding' nodes from 
DSGraphs while they are forwarding.  When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted.  This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

2cca3008e8 One of the 'annoying' things about ilists is that the iterators don't behave 
quite the same as for non-intrusive lists of pointers to nodes.  To support
transitioning code bases, add a new 'compatibility' iterator.

0b8cb2bc47 Change live interval representation. Machine instructions now have two 
slots each. As a concequence they get numbered as 0, 2, 4 and so
on. The first slot is used for operand uses and the second for
defs. Here's an example:

0: A = ...
2: B = ...
4: C = A + B ;; last use of A

The live intervals should look like:

A = [1, 5)
B = [3, x)
C = [5, y)

4f02fc28eb Fix PR223: Loopsimplify incorrectly updates dominator information 
The problem is that the dominator update code didn't "realize" that it's
possible for the newly inserted basic block to dominate anything.  Because
it IS possible, stuff was getting updated wrong.

3b303d91d7 In a "seeing the forest through the trees" kinda situation, I realized that a 
complete rewrite of load-vn will make it a bit faster.  This changes speeds up
the gcse pass (which uses load-vn) from 25.45s to 0.42s on the testcase in
PR209.

I've also verified that this gives the exact same results as the old one.
