[PATCH 00/10, OpenACC] Rework handling of OpenACC kernels regions

[Kwok Cheung Yeung]

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
