On s390 all ifunc resolvers were implemented in multiarch/ifunc-resolve.c. The resulting single object files has undefined references to all ifunc-functions. This patch introduces one multiarch/<func>.c file for each of memcpy, memcmp and memset with the function specific ifunc resolver. The different function implementations are now implemented in multiarch/<func>-s390x.S (moved from multiarch/<func>.S). The new multiarch/ifunc-resolve.h file contains the ifunc-resolver macro and other helper-macros. They are merged and are now used in common for 32/64bit. Therefore the __<func>_g5/__<func>_z900 functions were renamed to __<func>_default. This patch also enables testing the ifunc implementations by implementing the function __libc_ifunc_impl_list. It uses the helper-macros of ifunc-resolve.h.
