No problem, I'm using GDC anyway which might detect those in the back end.

An efficient implementation would certainly use at least an xor for 0
initialisation, and the other tricks will get different mileage depending on
the length of the pipeline surrounding. Not accessing memory is always better
if there are pipeline cycles to soak up the latency.
