[eigen] speed with g++-4.2

[Benoît Jacob <jacob@xxxxxxxxxxxxxxx>]

Hi List,

Following Michael's post I upgraded to g++ 4.2.1 and I get results similar to 
his. In my small benchmark, the speed of eigen2 with g++-4.2 is 4x faster 
than eigen2 with g++-4.1, and 10% faster than tvmet with g++-4.2.

Even better, this is with the latest svn revision in which the __restrict__'s 
have been removed. So it looks like we won't need to use restricted pointers, 
which is relieving.

Cheers,
Benoit
