CodeGen: Introduce splitCodeGen and teach LTOCodeGenerator to use it. llvm::splitCodeGen is a function that implements the core of parallel LTO code generation. It uses llvm::SplitModule to split the module into linkable partitions and spawning one code generation thread per partition. The function produces multiple object files which can be linked in the usual way. This has been threaded through to LTOCodeGenerator (and llvm-lto for testing purposes). Separate patches will add parallel LTO support to the gold plugin and lld. Differential Revision: http://reviews.llvm.org/D12260 llvm-svn: 246236
