Summary: Implements AsmWriter support for printing the module summary index to assembly with the format discussed in the RFC "LLVM Assembly format for ThinLTO Summary". Implements just enough of the parsing support to recognize and ignore the summary entries. As agreed in the RFC thread, this will be the behavior when assembling the IR. A follow on change will implement parsing/assembling of the summary entries for use by tools that currently build the summary index from bitcode.
