Refactor the ARM target parsing to use a def file with macros to expand
the necessary tables. This will allow me to restructure the code and structures using this to be significantly more efficient. It also removes the duplication of the list of several enumerators. It also enshrines that the order of enumerators match the order of the entries in the tables, something the implementation code actually uses. No functionality changed (yet). llvm-svn: 246370
