Avoids the first doubling for EdDSA signatures

The overhead of this first multiplication is not much, but it's
measurable.

Note the use of a macro for the constant time lookup and addition. It
could have been a function, but the function call overhead eats up all
the gains (I guess there are too many arguments to push to and pop from
the stack).
