This makes things into a new pass, currently disabled by default. I have attempted to copy what the unrolled does, without duplicating too much code. Pragmas and options should work, although I will need to add a few more tests for the different behaviours. I have tried to make it so that any unroll pragma will prevent unroll-and-jam, and added equivalent options/pragmas for unroll and jam. It still uses the unroll code as much as possible.

I have the clang side of the pragmas too, which I'll put up (although they may only even be useful for testing).
