[heading `BOOST_HW_SIMD_X86_FMA4`]
[@https://en.wikipedia.org/wiki/FMA_instruction_set FMA4] x86 extension.
Version number is the default BOOST_VERSION_NUMBER_AVAILABLE.
This extension is only available on particular CPUs. It does imply
AVX and SSE4a, but it is not implied by extensions newer than SSE3.
For example, AVX2 does not imply it.
