George Koehler 66f93f08c5 Add fef 4, fif 4. Improve fef 8, fif 8. Other float changes.
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.
