arm64/gcc-13: error: this operation requires the SVE ISA extension

I cannot build highway on arm64. Seems to fails with the following error:

There is a GCC 13 bug that happens on aarch64-linux-gnu when -O3 is enabled, and the issue can be worked around by appending -DCMAKE_CXX_FLAGS_RELEASE="-O2 -DNDEBUG" to the cmake command line.

@johnplatts

There is a GCC 13 bug

I assumed no one has reported it yet. Let me further reduce it to pass the bugzilla gate keeper. Closing as invalid.
