clear Mod/Ref bits of callers before inlining into a function.

Implement a new mergeInGraph method, which basically factors code out of

the BU class.
This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.
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. :)
