Summary: Adds assembly parsing support for the module summary index (follow on to r333335 which added the assembly writing support). I added support to llvm-as to invoke the index parsing, so that it can create either a bitcode file with a Module and a per-module index, or a combined index without a Module. I will send follow on patches soon to do the following: - add support to tools such as llvm-lto2 to parse the per-module indexes from assembly instead of bitcode when testing the thin link. - verification support. Depends on D47844 and D47842. Reviewers: pcc, dexonsmith, mehdi_amini Subscribers: inglorion, eraman, steven_wu, llvm-commits Differential Revision: https://reviews.llvm.org/D47905 llvm-svn: 335602
