Move arch/x86/util/dwarf-regs.c to util/dwarf-regs-x86.c and compile in unconditionally. To avoid get_arch_regnum being duplicated, rename to get_x86_regnum and add to get_dwarf_regnum switch. For get_arch_regstr, this was unused on x86 unless the machine type was EM_NONE. Map that case to EM_HOST and remove get_arch_regstr from dwarf-regs-x86.c.
