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

* 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.

* Add capability to recognize alias properties of the following common cases:
...
- A[c1] cannot alias A[c2] where constants c1 != c2
- A[i] cannot alias B[j] if A & B are provably different arrays
This should help out array based codes. For example, from bzip2 from spec,
3 additional loads can be GCSE'd, and _21_ additional loads can be LICMd due
to this change.
In a test example from the Spec GAP benchmark (vecffe.c), this change allows
_52_ additional loads to be GCSE'd and _224_ additional LICM'd loads.
Not bad for such a simple change. Other testcases show no change at all
because they just don't use arrays. Not too suprising there.

This file implements the top-down propagation pass for data structure graphs.
...
Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.
