Endian: Remove old special integer bitfields

The only way to use them was to put them in a union and then write all
the members of the union to set the various bit ranges. As only one
member of a union can be active at any time, the compiler is free to
optimize those writes away, though. This has started happening in the
wild now.

As we have a replacement, we can remove the old and broken code now.
