Remove another hasRawTextSupport.
To remove this one simply move the end of file logic from the asm printer to the target mc streamer. This removes the last call to hasRawTextSupport from lib/Target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200590 91177308-0d34-0410-b5e6-96231b3b80d8
