be used, but it's a starting point.  When I have more time I will whip this into
better shape.

This fixed PR16 "[lowerinvoke] The -lowerinvoke pass does not insert calls to setjmp/longjmp"

This causes the JIT, or LLC'd program to print out a nice message, explaining
WHY the program aborted.

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.

because we now create constantexprs for the constants instead of failing the
fold.

* Implement SCCP of load instructions, implementing Transforms/SCCP/loadtest.ll
  This allows us to fold expressions like "foo"[2], even if the pointer is only
  a conditional constant.

Fix iterator invalidation problems which was causing -mstrip to miss some
