# float census -- classes that separate the 'bits' and 'canonical'
# policies are: negative zero, NaN.  Classes an x87 -> SSE port is
# most likely to move are: subnormal, and anything near FLT_MAX.

'canonical' would change 0 leaf/leaves across the corpus (a no-op today).
subnormals: 0  (each one is an x87/SSE parity risk)
