HeCBench: matrixT-hip benchmark fails due to missing cooperative groups support

[kballeda]

I find that co-operative groups support related compile error for matrixT-hip benchmark.
Do we have a support for co-operative groups in chipStar, also I ran the same benchmark on AMD Mi250 and it was successful.

Benchmark: matrixT-hip in HeCBench
Compile Error:

HeCBench/src/matrixT-hip$ make
hipcc  -std=c++14 -Wall -O3 -c main.cu -o main.o
main.cu:33:16: error: expected namespace name
namespace cg = cooperative_groups;
               ^
main.cu:81:3: error: use of undeclared identifier 'cg'
  cg::thread_block cta = cg::this_thread_block();

No support for co-operative groups yet.
