80614ee5ef Implement optimization for direct function call case. This dramatically 
reduces the number of function nodes created and speeds up analysis by
about 10% overall.

5965bbb02f 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.

04aee9478c Two bug fixes: 
(1) Make entries for Constant values in the ScalarMap.
(2) Set MOD bit for the node pointed to by the
    argument of a free instruction.

0d5559fdfb Fix several related bugs in DSNode::mergeWith() caused by the 
fact that the incoming nodes may be merged away at intermediate
steps.  Use an extra level of indirection via DSNodeHandles
to track the nodes being merged.  All this now happens in a
static helper function MergeNodes().

bfff743897 Cute bug fix: when moving links from N to this, some links could have 
been missed if node *this got merged away due to recursive merging!
Also, links were not moved correctly if a node is collapsed.

2d2303db22 Fix logical error in TD pass: we should clear Mod/Ref bits of each caller 
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

16eac628f4 Pass to compute various statisics related to DSGraphs. 
For now, this just computes the #indirect call sites and
the avg. #callees per indirect call site (actually it prints
both totals and the average is their ratio).

dcb4ac9594 Fix two bugs: 
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.
