2 builds compete: 16-bit CCA adders.

Fastest

#	Build	Latency	Volume
1	16-bit Carry Cancel Adder 2 copies of a 8-bit build, stacked unnecessarymb	4 ticks	2560 blocks per copy
2	16-bit torchless Carry Cancel Adder Aminotreal	7 ticks	1960 blocks

#	Build	Volume	Latency
1	16-bit torchless Carry Cancel Adder Aminotreal	1960 blocks	7 ticks
2	16-bit Carry Cancel Adder 2 copies of a 8-bit build, stacked unnecessarymb	2560 blocks per copy	4 ticks

Each is smaller than every build at least as fast, so going slower buys space.
