Add options `--forcegpu` and `--profile`

This PR:

• Restore the --forcegpu option to enforce kernels to run on the GPU whenever a CUDA implementation is available.
• Restore the --profile option to display the performance profile of each kernel and their distribution among the resources.
• Add a cmake option CHAMELEON_SIMULATION_EXTENDED to enable non GPU kernels to be easily simulated on the GPU through simgrid.

changed milestone to %Chameleon 1.1.0

added Feature SimGrid StarPU labels

@mverite Should be ok for you. I'll check that it compiles with all configurations, and merge if that's ok. @agullo please review.

@all Ready for review. This PR may be of interest to all users using SimGrid as it allows to easily simulate any kernel on the GPU by applying similar changes to the codelet as the one applied to POTRF in this PR:

-CODELETS_CPU(zpotrf, cl_zpotrf_cpu_func)
+#if defined(CHAMELEON_SIMULATION) && defined(CHAMELEON_SIMULATION_EXTENDED)
+CODELETS( zpotrf, cl_zpotrf_cpu_func, cl_zpotrf_cuda_func, STARPU_CUDA_ASYNC )
+#else
+CODELETS_CPU( zpotrf, cl_zpotrf_cpu_func )
+#endif

@fpruvost @agullo Do you approve or not ? thanks

Thanks much @faverge . This is a great feature and as always extremely well integrated. I am just not sure what should happen if gpus are forced but no gpu is there. It may just be perfect like it is.
