Decompose OpenACC 'kernels' constructs into parts, a sequence of compute constructs (was: [og8] OpenACC 'kernels' construct changes: splitting of the construct into several regions)

Hi Thomas,

regarding the new option:

+fopenacc-kernels=
+C ObjC C++ ObjC++ RejectNegative Joined Enum(openacc_kernels) Var(flag_openacc_kernels) Init(OPENACC_KERNELS_PARLOOPS)
+-fopenacc-kernels=[decompose|parloops]	Specify mode of OpenACC 'kernels' constructs handling.

Do you intent that users will switch between those two options?

Or is this new option only an interim solution until decompose is handled?

If the latter, maybe using a --param makes more sense than keeping the later for ever.
