When I wrote fef 8, I forgot to test denormalized numbers. Oops. Now fix two of my mistakes: - When checking for zero, `extrwi r6, r3, 22, 12` needs to be `extrwi r6, r3, 20, 12`. There are only 20 bits to extract. - After the multiplication by 2**64, I forgot to put the fraction in [0.5, 1) or (-1, 0.5] by setting IEEE exponent = 1022. Teach fif 8 about signed zero and NaN. In ncg/table, change cmf so NaN is not equal to any value, and comment why ordered comparisons don't work with NaN. Also add cost for fctwiz, remove extra `uses REG`. Edit comment in cfu8.s because the conditional branch might be before or after fctwiz.
