Fix bitcode auto-upgrade when using bitcode lazy loading The auto-upgrade path could be called before the VST (global names) was fully parsed, and thus intrinsic names were not available and the autoupgrade logic could not operate. Fix link failures with ThinLTO. This is a recommit of r278610 with a different fix. llvm-svn: 278615

Fix test change in r290736: restore index generation I remove one extra line, but because annoyingly llvm-lit does not clean the output directory before running the test, it didn't fail locally (the file was present from a previous run). llvm-svn: 290740

; We can't use llvm-dis here, because it would do the autoupgrade itself.
Replace test from using llvm-lto to use llvm-link (NFC) Some incoming changes in ThinLTO will break this test. Instead of relying on the heuristic to import, we force the importing to happen with llvm-link. llvm-svn: 290736

Bitcode: Add a string table to the bitcode format. Add a top-level STRTAB block containing a string table blob, and start storing strings for module codes FUNCTION, GLOBALVAR, ALIAS, IFUNC and COMDAT in the string table. This change allows us to share names between globals and comdats as well as between modules, and improves the efficiency of loading bitcode files by no longer using a bit encoding for symbol names. Once we start writing the irsymtab to the bitcode file we will also be able to share strings between it and the module. On my machine, link time for Chromium for Linux with ThinLTO decreases by about 7% for no-op incremental builds or about 1% for full builds. Total bitcode file size decreases by about 3%.

[ThinLTO] Add string saver onto index for value names Summary: Adds a string saver to the ModuleSummaryIndex so it can store value names in the case of adding a ValueInfo for a GUID when we don't have the name stored in a Module string table. This is motivated by the upcoming summary parser patch, where we will read value names from the summary entry and want to store them, even when a Module is not available. Currently this allows us to store the name in the legacy bitcode case, and I have added a test to show that.
