Start using the AttributesImpl object to hold the value of the attributes. All queries go through the interfaces now. This has one unfortunate consequence. I needed to move the AttributesImpl.h file into include/llvm. But this is only temporary! Otherwise, the changes needed to support this would be too large. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165433 91177308-0d34-0410-b5e6-96231b3b80d8
