Another strange thing is that 000fc000 does not have 'fc' byte-aligned
inside CR, if you see what I mean.  If it was 0000fc00 or 00fc0000, some
byte-inversion mistake would seem likely.

This isn't a 74xx specific result.  I'm sure any ppc should produce
00004000.  The test is very simple: make CR=0 then do crorc 17,14,15.
So only 1 bit in CR will then be set - all others are zero.
