Enable conditional expressions in splitting coercions.

Browse source 
ncgg has parsed the optional conditional expression (optexpr) of each
splitting coercion since commit 72b83cc in 1985; but for almost 33
years, ncg has ignored the expression in c2_expr.

Few tables had conditional coercions (I only found them in arm and
m68020), and no tables had conditional splitting coercions, so this
only becomes a problem now as I try to add a conditional splitting
coercion to powerpc.
