3fe4d3cb5b Malloc/Free have mod/ref effects. Do not allow CSE of function calls that

b81c021f14 Change the call graph class to have TWO external nodes, making call graph 
SCC passes much more useful.  In particular, this should fix the incredibly
stupid missed inlining opportunities that the inliner suffered from.

ba12c23ca7 Including the symbol table in the FindUsedTypes analysis was the WRONG way
