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 internal/private GVs implicitly dso_local. While updating clang tests for having clang set dso_local I noticed that: - There are *a lot* of tests to update. - Many of the updates are redundant. They are redundant because a GV is "obviously dso_local". This patch starts formalizing that a bit by requiring that internal and private GVs be dso_local too. Since they all are, we don't have to print dso_local to the textual representation, making it a bit more compact and easier to read. llvm-svn: 322317

Have a single way for creating unique value names. We had two code paths. One would create names like "foo.1" and the other names like "foo1". For globals it is important to use "foo.1" to help C++ name demangling. For locals there is no strong reason to go one way or the other so I kept the most common mangling (foo1). llvm-svn: 253804
