callgraph, when one member of a SCC calls another then the analysis would drop to mod-ref because there is (usually) no function info for the callee yet; fix this. Teach the analysis about function attributes, in particular the readonly attribute (which requires being careful about globals). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55696 91177308-0d34-0410-b5e6-96231b3b80d8
