Write the identifier offsets array into the PCH file as a blob, so that the PCH reader does not have to decode the VBR encoding at PCH load time. Also, reduce the size of the identifier offsets from 64 bits down to 32 bits. The identifier table itself isn't going to grow to more than 4GB :) Overall, this results in a 13% speedup in the Cocoa-prefixed "Hello, World" benchmark. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70063 91177308-0d34-0410-b5e6-96231b3b80d8
