Instead of defining DWARF register to string table in dwarf-regs-table.h and dwarf-regs.c, use a common table in dwarf-regs-table.h. Ensure that the DWARF register table is up-to-date with http://refspecs.linuxfoundation.org/ELF/zSeries/lzsabi0_s390/x1542.html. For unwinding with libdw, also ensure to correctly setup the DWARF register frame according to the register mappings. Currently, libdw supports up to 32 registers only.
