Add an ArchEnum to express the arch of the Elf objects and Reg objects. Split out the regs code into per arch pieces and generic parts. Also, split out the header files for each arch. Do not break out the test code yet, there isn't enough and it doesn't help to maintain the tests. Test: libunwindstack/libbacktrace/debuggerd unit tests pass. Test: Running debuggerd -b <PIDS> yields valid data on bullhead. Change-Id: If61f6c730c9ff2249f986b41de8c4d62f7158325
