When using Xcode version 14.3 on Apple Silicon hardware a number of regression tests fails. This change fixes this problem. The root cause comes to the floating point contraction. It was already disabled for GCC on Linux, but not for Clang on neither of Linux or macOS. Also corrected the comment about Clang default, as it as set to on somewhere in 2021.
