[S390] remove ieee_instruction_pointer from thread_struct
The ieee_instruction_pointer can not be read from user space anymore
since git commit 613e1def6b52c399a8b72a5e11bc2e57d2546fb8, the ptrace
interface always returns zero. Remove it from the thread_struct. It
is still present in the user_regs_struct for compatability reasons.
