Alexey Bataev e9bfa1dd38 [OPENMP]Use new interface for task reduction. 
Summary:
Patch forces codegen to use the new runtime functions for task reductions where
the issue with passing the address of the original variables to the UDR
initializers is fixed. Also, this patch is required for upcoming
support of task modifier inreduction clause.

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.
