commit 3d9889977397098d14c5be50f1dfef1c3eeb508f

    PR10491 Don't assign to REG_IP if it isn't an lvalue (s390 and ia64).
    
    To fixup REG_IP to show the correct value after a [ku]probe trap we
    assigned the address of the actual instruction pointer of the probed
    instruction. That doesn't work on architectures, s390 and ia64, where
    REG_IP is not a simple lvalue. Just don't try to fixup the address in
    those cases. If this isn't enough, the uprobe_stmt_num.exp testcase
    will point this out.
    
    * runtime/regs.h: Define REG_IP_LVALUE for x86_64, i386, powerpc64 and arm.
    * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Only fixup
      REG_IP when REG_IP_LVALUE is defined.
      (uprobe_derived_probe_group::emit_module_decls): Likewise.
      (kprobe_derived_probe_group::emit_module_decls): Likewise.
