          Platform: All

          Severity: Normal
          Priority: P2

We currently only cache plain webkit strings in externalized v8 strings and
then convert them on demand to atomic strings.  With this change we also cache
the atomic strings the first time they are created.

Also, cleaned up some code in the v8 code generator and added a hint that the
parameter to getElementById is actually an atomic string.  We may want to do
that in more places but I'm leaving that for another changelist.
