[ThinLTO] Add option to emit imports files for distributed backends Summary: Add support for emission of plaintext lists of the imported files for each distributed backend compilation. Used for distributed build file staging. Invoked with new gold-plugin thinlto-emit-imports-files option, which is only valid with thinlto-index-only (i.e. for distributed builds), or from llvm-lto with new -thinlto-action=emitimports value. Depends on D19556. Reviewers: joker.eph Subscribers: llvm-commits, joker.eph Differential Revision: http://reviews.llvm.org/D19636 llvm-svn: 269067

[ThinLTO] Use std::map to get determistic imports files Summary: I noticed that the .imports files emitted for distributed ThinLTO backends do not have consistent ordering. This is because StringMap iteration order is not guaranteed to be deterministic. Since we already have a std::map with this information, used when emitting the individual index files (ModuleToSummariesForIndex), use it for the imports files as well. This issue is likely causing some unnecessary rebuilds of the ThinLTO backends in our distributed build system as the imports files are inputs to those backends.

[ThinLTO] Always emit a summary when compiling in ThinLTO mode Summary: Emit an empty summary section, instead of no summary section, when there are no global variables in the index. This ensures that LTO will treat these files as ThinLTO inputs, instead of as regular LTO inputs. In addition to not being what the user likely intended when compiling with -flto=thin, the current behavior is problematic for distributed build systems that expect to get ThinLTO index and imports files back for each input compiled with -flto=thin. Combining into a single regular LTO module also reduces the backend parallelism. And in the case where the index was suppressed due to uses in inline assembly, combining into a single LTO module could provoke renaming of duplicates that we were trying to prevent by suppressing the index. This change required a couple of fixes to handle the empty summary section.
