171de656eb An initial implementation of an LLVM ProfileInfo class which is designed to

4ff0b9636d Substantially improve the DSA code by removing 'forwarding' nodes from 
DSGraphs while they are forwarding.  When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted.  This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

e187d56520 Abstract out the Nodes collection. Instead of providing a getNodes() method, 
provide node_begin/end iterators, which are only guaranteed to be
bidirectional, not random access.

2f561384fb Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.

8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter. 
Since this really only makes sense for these two, change hte instance variable
to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.

eae45cf44b The recalclulate method was a nasty hack that was once used by the -cee pass,

this method anymore anyway, so eliminate the method.
