a new getSectionForMergableConstant hook. This removes one dependence of TAI on Type, and provides the hook with enough info to make the right decision based on whether the global has relocations etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76705 91177308-0d34-0410-b5e6-96231b3b80d8
