TransformUtils: Introduce module splitter. The module splitter splits a module into linkable partitions. It will be used to implement parallel LTO code generation. This initial version of the splitter does not attempt to deal with the somewhat subtle symbol visibility issues around module splitting. These will be dealt with in a future change. Differential Revision: http://reviews.llvm.org/D12132 llvm-svn: 245662

Make GlobalValues with non-default visibilility dso_local. This is similar to r322317, but for visibility. It is not as neat because we have to special case extern_weak. The idea is the same as the previous change, make the transition to explicit dso_local easier for the frontends. With this they only have to add dso_local to symbols where we need some external information to decide if it is dso_local (like it being part of an ELF executable). llvm-svn: 322806
