Overall saving are small because the effect is blurred by the code that
does not allocate vectors - my patch has 0 effect on such code.

Calculations involving vectors are pidigits that is 30% faster and
bignum version of fib.el - over 50% faster.

If you know any useful code that makes heavy use of vector allocation, I
can also benchmark it.
