This pass is required by the Midgard compiler; our instruction set uses NIR-style booleans (~0 for true) but lacks a dedicated b2f instruction. Normally, this lowering pass would be implemented in a backend-specific algebraic pass, but this conflicts with the existing iand->b2f pass in nir_opt_algebraic.py, hanging the compiler. This patch thus makes the existing pass optional (default on -- all other backends should remain unaffected), adding an optional pass for lowering the opposite direction. v2: Defer lowering until late algebraic optimisations to allow optimising the b2f instruction itself.
