Eh, haswell added the movbe instructions. And I wouldn't be surprised if someone in the RISCV world added big endian instructions (they're nice for network processing).
And nearly every powerpc I've seen is big endian, FWIW.

The Atom needs instructions that make bigger, more complex operations simpler and lower powered, and with transistors the size they are these days they have ample silicon space to burn on these types of accelerators.
