use XCore-specific section with xcore specific cp/dp flags to restore
support for globals going into the appropriate sections with the flags. This hopefully finishes unbreaking the previous behavior that I broke before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79079 91177308-0d34-0410-b5e6-96231b3b80d8
