Teresa Johnson f638013746 [ThinLTO] Import composite types as declarations ... Summary: When reading the metadata bitcode, create a type declaration when possible for composite types when we are importing. Doing this in the bitcode reader saves memory. Also it works naturally in the case when the type ODR map contains a definition for the same composite type because it was used in the importing module (buildODRType will automatically use the existing definition and not create a type declaration). For Chromium built with -g2, this reduces the aggregate size of the generated native object files by 66% (from 31G to 10G). It reduced the time through the ThinLTO link and backend phases by about 20% on my machine.
