This is first step in reworking how mach-o relocations are processed. The existing KindHandler is going to become a delgate/helper object for processing architecture specific references. The KindHandler knows how to convert mach-o relocations into References and back, as well, as fixing up the content the relocation is on. One of the messy things about mach-o relocations is that they sometime come in pairs, but the pairs still convert to one lld::Reference. So, the conversion has to detect pairs (arch specific) and change the stride. llvm-svn: 211921
