fixed-size mpn_mul_n for small n?

[Zimmermann Paul]

       Hi,

GMP currently has variable-size assembly code for mpn_mul_n on some
processors. Could it be faster to have fixed-size assembly code for
small values of n (say up to n=32)? Then mpn_mul_n() would simply be
a wrapper to those fixed-size functions, or to a variable-size code
for n>32.
