Timothy Flynn 8b23bbf58e LibJS: Read properties from the Intl.DateTimeFormat options object once
This is a normative change in the ECMA-402 spec. See:
02bd03a

This is observable just due to reading the properties one less time. It
would have been possible for e.g. the property values to change between
those invocations.
