Hi,

I have found that adding the following checking assert very useful
when debugging omp lowering issues, so I have added it to the hsa
branch.  I hope that nobody will mind, but it of course is not an
essential thing to have if someone does.

Thanks,

Martin

	* omp-low.c (scan_omp_1_op): Add checking assert that we are not
	re-mapping to ERROR_MARK.
