The zero length empty string returned by the static method StringImpl ::empty() should be created as an 8 bit string.
This will help performance when concatenated with other strings.

This patch provides no performance benefit by itself, but allows for future changes that concat null strings to use an 8 bit path.

Oh, I see now. The rationale is in the bug, but not the patch. Next time please put it in the patch.
