In order to minimize potential confusion regarding numbered labels
appearing in a different order in the assembler output due to the use of
subsections, use a named local label to jump back into the vector
handler code from the associated loop8 mitigation sequence.
Using \@ doesn't buy us much as \name is already unique. Maybe using
some kind of prefix would be better, e.g. .Lfoo_\name would be more
descriptive?
Fair point. I'll fix that.
