[pypy-issue] [issue892] Pypy is slower on longs than it should

In the attached file rbigint_xmul.py there is a modified _x_mul for 
rbigint.py in pypy-2.2.1,
ported from a patch I submitted in http://bugs.python.org/issue3944

On my computer (x86_64) multiplication seems to be at least as fast as 
CPython for numbers with few words,  about 2x faster for numbers 
with about 15 words, about 1.8x faster for numbers with 150 words.
