[pstl] openmp backend implementation progress

Hi friends,

I have finished implementing the parallel partial sort algorithm. However, I am having trouble testing it because the compiler crashes on the code. I realize my tree is pretty out of date at this point.

I think that I am ready to submit a patch, since the last algorithm I need to implement is parallel merge. While I am implementing that, I’m sure that the code needs a thorough review. In order to facilitate that, what is the best way to go? Should I check out a fresh tree and try to apply my patch on that, and then submit it?

Should I make a patch of my current changes off the last rebase and submit that instead?

Please let me know.
