Improve polynomial doubling code, move to util
Now does 64-bits at a time instead of 8 bits, and avoids conditional
timing channel on the XOR carry. Confirmed that at least GCC 7 and
Clang 4 on x86-64 compile the functions without conditional jumps.
Also removes CMAC as a dependency of OCB, which only needed it in
order to call CMAC::poly_double
