Fix boolean float conversion and product warnings.
This fixes some gcc warnings such as: ``` Eigen/src/Core/GenericPacketMath.h:655:63: warning: implicit conversion turns floating-point number into bool: 'typename __gnu_cxx::__enable_if<__is_integer<bool>::__value, double>::__type' (aka 'double') to 'bool' [-Wimplicit-conversion-floating-point-to-bool] Packet psqrt(const Packet& a) { EIGEN_USING_STD(sqrt); return sqrt(a); } ``` Details: - Added `scalar_sqrt_op<bool>` (`-Wimplicit-conversion-floating-point-to-bool`). - Added `scalar_square_op<bool>` and `scalar_cube_op<bool>` specializations (`-Wint-in-bool-context`) - Deprecated above specialized ops for bool. - Modified `cxx11_tensor_block_eval` to specialize generator for booleans (`-Wint-in-bool-context`) and to use `abs` instead of `square` to avoid deprecated bool ops.
