This series of patches reworks the way that OpenACC kernels regions are 
processed by GCC. Instead of relying on the parloops pass for 
auto-parallelisation of the kernel region, the contents of the region are 
transformed into a sequence of offloaded regions, which are then processed 
individually.

Tested on an x86_64 host, with offloading to a Nvidia Tesla K20c card.

Okay for trunk?

Thanks

Kwok

So, what is the state of this series?  Has Thomas reviewed it and acked from
OpenACC side?  Which particular patches you want me to look at from the
OpenMP vs. OpenACC interaction?
