This patch introduces generic x86-64 edge kinds, and refactors the MachO/x86-64 backend to use these edge kinds. This simplifies the implementation of the MachO/x86-64 backend and makes it possible to write generic x86-64 passes and utilities. The new edge kinds are different from the original set used in the MachO/x86-64 backend. Several edge kinds that were not meaningfully distinguished in that backend (e.g. the PCRelMinusN edges) have been merged into single edge kinds in the new scheme (these edge kinds can be reintroduced later if we find a use for them). At the same time, new edge kinds have been introduced to convey extra information about the state of the graph. E.g. The Request*AndTransformTo** edges represent GOT/TLVP relocations prior to synthesis of the GOT/TLVP entries, and the 'Relaxable' suffix distinguishes edges that are candidates for optimization from edges which should be left as-is (e.g. to enable runtime redirection). ELF/x86-64 will be refactored to use these generic edges at some point in the future, and I anticipate a similar refactor to create a generic arm64 support header too.
