When predicating the code for OpenACC, we should avoid the entry block
in an offloaded region, which contains setup code that should be run in
every thread. The following patch adds a new marker statement that is
used to identify this block. Currently, predication doesn't happen
anyway due to an oversight in the algorithm, but I'll be fixing that in
a followup patch.

Committed on gomp-4_0-branch.


Hi Bernd,

this causes an ICE in kernels-eternal.c.

I don't see this test on my branch checkout - is it something you areusing locally?
