This is a strange diff. Is there a conflict?

Just the system thinking this is a modified copy of an existing file rather than
a new file. Add --no-find-copies to git cl upload if it becomes a problem.

OK. The spec changed to the attribute from 'cores' to 'hardwareConcurrency' so
this patch needs to make that change.

+    readonly attribute unsigned long cores;
 };
