Move methods out-of-line.
The internal representation of the Attributes class will be opaque. All of the query methods will need to query the opaque class. Therefore, these methods need to be out-of-line. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165305 91177308-0d34-0410-b5e6-96231b3b80d8
