You need to make this change in deoptimizer-arm.cc as well.

Thanks for the reminder. I actually indented to do the port after the ia32 part
is LGTM'ed, but forgot to mention it. Now the port is done.

-    int deoptimization_index = table.GetDeoptimizationIndex(i);
-    int gap_code_size = table.GetGapCodeSize(i);
+    SafepointEntry safepoint_entry = table.GetEntry(i);
+    int deoptimization_index = safepoint_entry.deoptimization_index();
+    int gap_code_size = safepoint_entry.gap_code_size();
