Yes. The 'not', 'abs', 'bnot', and 'bnots' opcodes already have 
2-argument variants, the 'n_*' alternates are unnecessary.

The task also involves modifying the corresponding vtable functions 
('logical_not', 'absolute', 'binary_not', 'binary_nots') so they return 
a new PMC, rather than morphing the existing destination PMC. (Many of 
them already do this, so the 'n_*' variants were actually already doing 
the same thing as the regular opcodes.)
