New description:
Add a patch from Paul Zimmermann which significantly speeds up MPC
multiplication.
'''Timings''' (time in microseconds for 1 multiplication on an `Intel(R)
Core(TM) i7-2640M CPU @ 2.80GHz`):
||Prec (bits)||= `ComplexField` =||= `MPComplexField` (old)=||=
`MPComplexField` (new)=||
||53||0.53||1.09||0.81||
||128||0.56||1.18||0.90||
||360||0.77||1.47||1.12||
||1024||1.74||3.98||3.39||
