From 5f0b4a4010af4cbf6161a0d1a03a747addc44a5d Mon Sep 17 00:00:00 2001

Date: Fri, 5 Mar 2021 13:16:43 +0100
Subject: 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.
