eigen/test/mapped_matrix.cpp
Benoit Steiner 7ed9441ea4 Reverted the definition of the EIGEN_ALIGN to its former meaning (i.e. a boolean)
Created a new EIGEN_ALIGN_BYTES define to encode how the data should be aligned
Fixed a few remaining alignment issues exposed when the Eigen code is compiled with avx enabled.
Created a new EIGEN_ALIGN_DEFAULT define, which is set to the minimum alignment value required for the chosen instruction set. Use this value instead of EIGEN_ALIGN32 to preserve the existing alignment on SSE/Altivec/Neon.
