We need the support for per-team shared variables to support codegen for
lastprivates/reductions. Patch adds this support by using shared memory
if the total size of the reductions/lastprivates is <= 128 bytes,
then  pre-allocated buffer in global memory if size is <= 4K bytes,or
uses malloc/free, otherwise.
