OpenMP/PolyInt: Pass poly-int structures by address to OMP libs.
Currently poly-int type structures are passed by value to OpenMP runtime
functions for shared clauses etc. This patch improves on this by passing
around poly-int structures by address to avoid copy-overhead.
gcc/ChangeLog:
* omp-low.cc (use_pointer_for_field): Use pointer if the OMP data
structure's field type is a poly-int.
