Comment (by rwbarton):

 Anecdotally it's fairly common to see ugly long strings of `mov`
 instructions in generated code, though I don't know whether they are from
 cases like this one, the similar but distinct case of
 ticket:10980#comment:13, or something completely different like record
 updates in a record with many fields.
