I did runs of the shader-db/run program with valgrind/callgrind 

Here the original merge_registers reports 0.21% and my code reports
0.50%. 

If it is important to cut down on these addes 0.3%, I think, I can
eliminate 0.1% by changing the implementation to not used so many
dynamically allocated objects, but beyond that it will be difficult.

Best,
