543e34ab9d Re-implement move assignments. 
The original swap approach leads to potential undefined behavior (reading
uninitialized memory) and results in unnecessary copying of data for static
storage.

Here we pass down the move assignment to the underlying storage.  Static
storage does a one-way copy, dynamic storage does a swap.

Modified the tests to no longer read from the moved-from matrix/tensor,
since that can lead to UB. Added a test to ensure we do not access
uninitialized memory in a move.

Fixes: #2119

5f0b4a4010 Revert "Adds EIGEN_CONSTEXPR and EIGEN_NOEXCEPT to rows(), cols(), innerStride(), outerStride(), and size()" 
This reverts commit 6cbb3038ac48cb5fe17eba4dfbf26e3e798041f1 because it
breaks clang-10 builds on x86 and aarch64 when C++11 is enabled.
