c9452de8 - add wb_back on all task switch paths (#60617)

add wb_back on all task switch paths (#60617) Since this task's stack or scope field could have been modified after it was marked by an incremental collection (and not just for copy stacks), move the barrier back unconditionally here. --------- Co-authored-by: Valentin Churavy <v.churavy@gmail.com> Co-authored-by: Jeff Bezanson <jeff.bezanson@gmail.com> (cherry picked from commit 14ca1abc7237fc586d71d8b1b2c5a2d08bc2276e)
