5da09703fa * Fix a bug where global incompleteness marking would not mark the global
itself incomplete!
* Allow incompleteness callers to specify they don't want globals to be
  considered sources of incompleteness.

5f3ef2f0e7 Implement optimization for direct function call case. This dramatically
reduces the number of function nodes created and speeds up analysis by
about 10% overall.

d946a6a307 Fix a bug where we would incorrectly delete globals which had edges to alive nodes in
a graph in the t-d pass.  This slows down the TD pass by quite a bit (1/3), but is
needed for correctness.
