Failed on data

JDK-8346990 appears to have changed the format of data written out in the dump, such that reading it back is failing:

@@ -785,7 +785,7 @@ void ciMethodData::dump_replay_data(outputStream* out) {
    // We could use INTPTR_FORMAT here but that's zero justified
    // which makes comparing it with the SA version of this output
    // harder. data()'s element type is intptr_t.
- out->print(" " INTX_FORMAT_X, data()[i]);
+ out->print(" %#zx", data()[i]);
  }

The problem is in the formatting of zero. The original format specifier will produce 0x0 but the new one just a plain 0.
