I have started going through the code.  One question regarding the
approach: Why didn't you folks generate OMP_PARALLEL/OMP_FOR?  The
intent was for auto-parallelization passes to target the OMP IL, not
libgomp.

While not an expert on libgomp, I would certainly prefer that we target the OMP_* expressions as well, if possible. It might be possible, in future, to lower those to something other than libgomp; by confining the lowering to a single phase, we design for that possible future.
