Teresa Johnson d7c9485243 [ThinLTO] Move summary computation from BitcodeWriter to new pass ... Summary: This is the first step in also serializing the index out to LLVM assembly. The per-module summary written to bitcode is moved out of the bitcode writer and to a new analysis pass (ModuleSummaryIndexWrapperPass). The pass itself uses a new builder class to compute index, and the builder class is used directly in places where we don't have a pass manager (e.g. llvm-as). Because we are computing summaries outside of the bitcode writer, we no longer can use value ids created by the bitcode writer's ValueEnumerator. This required changing the reference graph edge type to use a new ValueInfo class holding a union between a GUID (combined index) and Value* (permodule index). The Value* are converted to the appropriate value ID during bitcode writing. Also, this enables removal of the BitWriter library's dependence on the Analysis library that was previously required for the summary computation.
