Saleem Abdulrasool f185e91e2b CodeGen: further loosen -O0 CG for WoA division
Generate the slowest possible codepath for noopt CodeGen.  Even trying to be
clever with the negated jump can cause out-of-range jumps.  Use a wide branch
instead. Although the code is modelled simplistically, the later optimizations
would recombine the branching into `cbz` if possible.  This re-enables the
previous optimization as well as hopefully gives us working code in all cases.
