Use a pointer as the relocation iterator.
Since the relocation iterator walks only the relocations in one section, we can just use a pointer and avoid fetching information about the section at every reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180262 91177308-0d34-0410-b5e6-96231b3b80d8
