Alexey Bataev b3998a0edb [OPENMP]Fix PR45047: Do not copy firstprivates in tasks twice.
Avoid copying of the orignal variable if it is going to be marked as
firstprivate in task regions. For taskloops, still need to copy the
non-trvially copyable variables to correctly construct them upon task
creation.
