Add numext::sqrt function to enable custom optimized implementation.

This changeset add two specializations for float/double on SSE. Those
are mostly usefull with GCC for which std::sqrt add an extra and costly
check on the result of _mm_sqrt_*. Clang does not add this burden.
In this changeset, only DenseBase::norm() makes use of it.
