Rematerialize nodes from the globals graph into the current graph
after all callees are inlined into the current graph. NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp, which ensures that resolvable indirect calls are not moved out to the globals graph, so that they are eventually inlined (if possible). llvm-svn: 7189
