[ThinLTO] Print module summary index to assembly 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.

[ThinLTO] Parse module summary index from assembly 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

[ThinLTO] Fix a few more test match issues Fix a few more bot failures due to r333335: - don't match path other than file name, since the delimiter is different for Windows - The summary IDs in thinlto-function-summary-refgraph.ll may vary and therefore can't be matched exactly, because the ordering depends on the iteration order of the index map which is keyed by GUID. The GUID for private values will depend on the path. llvm-svn: 333338
