Revert "[perl #117855] Store CopFILEGV in a pad under ithreads"

This reverts commit c82ecf346.

It turn out to be faulty, because a location shared betweens threads
(the cop) was holding a reference count on a pad entry in a particu-
lar thread.  So when you free the cop, how do you know where to do
SvREFCNT_dec?

In reverting c82ecf346, this commit still preserves the bug fix from
1311cfc0a7b, but shifts it around.
