Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.

Stop representing scalars as explicit nodes in the graph. Now the only

nodes in the graph are memory objects, which is very nice. This also greatly
reduces the size and memory footprint for DSGraphs. For example, the local
DSGraph for llu went from 65 to 13 nodes with this change. As a side bonus,
dot seems to lay out the graphs slightly better too. :)

This fixes all kinds of problems with array handling. There are still bugs to
...
be fixed, but we are getting much closer now.
* Make DSNode::TypeRec a full fledged DSTypeRec type.
* Add methods used to update and access the typerecords elements
* Add methods to query if and to cause a node to be completely folded
* DSGraph construction doesn't use the allocation type for anything at all,
now nodes get their type information based on how they are used.
* Fixed a bug with global value handling introduced in the last checkin
* GEP support is now much better, arrays are handled correctly. The array
flag is now updated in type records. There are still cases that are not
handled yet (we do not detect pessimizations), but getting much closer.
