Summary: Several fixes to the handling of bitcode files without function summary sections so that they are skipped during ThinLTO processing in llvm-lto and the gold plugin when appropriate instead of aborting. 1 Don't assert when trying to add a FunctionInfo that doesn't have a summary attached. 2 Skip FunctionInfo structures that don't have attached function summary sections when trying to create the combined function summary. 3 In both llvm-lto and gold-plugin, check whether a bitcode file has a function summary section before trying to parse the index, and skip the bitcode file if it does not. 4 Fix hasFunctionSummaryInMemBuffer in BitcodeReader, which had a bug where we returned to early while looking for the summary section. Also added llvm-lto and gold-plugin based tests for cases where we don't have function summaries in the bitcode file. I verified that either the first couple fixes described above are enough to avoid the crashes, or fixes 1,3,4. But have combined them all here for added robustness.
