Olivier Parcollet 552c440238 arrays : add ConstView to fix const correctness
- A()(0) = 1
will not work any more if A is const, as it should be.

- Introduced the notion of const_view, simply done by a flag
(flag 0, for easy debug)
- changed the slice of ISP to use it (only on C++11 compliant compiler)
- Move BoundCheck Flags to 5.
