Fix compilation issues with icc and g++ < 4.1. Those include:

Browse Source 
- conflicts with operator * overloads
 - discard the use of ei_pdiv for interger
   (g++ handles operators on __m128* types, this is why it worked)
 - weird behavior of icc in fixed size Block() constructor complaining
   the initializer of m_blockRows and m_blockCols were missing while
   we are in fixed size (maybe this hide deeper problem since this is a
   recent one, but icc gives only little feedback)
