--- Comment #2 from Ian Romanick <idr at freedesktop.org> ---
Looking at the commit, the reason for the regression is obvious.  The
nir_lower_bool_to_int32 pass happens after the last nir_opt_algebraic, so the
pattern in nir_opt_algebraic never sees a ('b2i32', 'a at 32').  It's effectively
dead code.
