[r41k0u]

We have fixed some binops tests and found grave issues with our typing system. I am in favour of merging this now, refactoring functions_pass and the grammar (so @varun-r-mallya can have a better time with vmlinux), and then coming back to this to fix our typing system and other issues. I have some ideas on how the typing system would be.
