This is a global interpreter variable that has long been unused - the last place I can find goes back to the year 2012. I think it's safe to remove it now.

This variable is no longer used in any perl code. It used to be used as
a temporary during some expression macros, similar to the way PL_Sv is
used. The last reference I can find to it in real code was removed in
2012, by the commit
  6702ba9

(It's a little late in the 5.39.x development cycle to consider removing
the line from intrpvar.h itself; but we could do that at the start of
5.41.x).
