[heading `BOOST_HW_SIMD_X86_SSE4A`]
[@https://en.wikipedia.org/wiki/SSE4##SSE4A SSE4A] x86 extension.
Version number is the default BOOST_VERSION_NUMBER_AVAILABLE.
This extension is only available on particular CPUs. It does imply
SSE3, but it is not implied by extensions newer than SSE3. For example,
SSE4.1 does not imply it.
