C The f functions,
C
C f1(x,y,z) = z ^ (x & (y ^ z))
C f2(x,y,z) = x ^ y ^ z
C f3(x,y,z) = (x & (y ^ z)) + (y & z)
C f4 = f2
C This form for f3 was suggested by George Spelvin. The terms can be
C added into the result one at a time, saving one temporary.
C The form of one sha1 round is
C
C a' = e + a <<< 5 + f( b, c, d ) + k + w;
