Richard Smith d88a7f1a92 Re-commit r246497 (and dependent changes r246524 and r246521), reverted in ... r246546, with a workaround for an MSVC 2013 miscompile and an MSVC 2015 rejects-valid. Original commit message: [modules] Rework serialized DeclContext lookup table management. Instead of walking the loaded ModuleFiles looking for lookup tables for the context, store them all in one place, and merge them together if we find we have too many (currently, more than 4). If we do merge, include the merged form in our serialized lookup table, so that downstream readers never need to look at our imports' tables. This gives a huge performance improvement to builds with very large numbers of modules (in some cases, more than a 2x speedup was observed). llvm-svn: 246582		2015-09-01 20:35:42 +00:00
