[@https://en.wikipedia.org/wiki/FMA_instruction_set FMA3] x86 extension.

Version number is the default BOOST_VERSION_NUMBER_AVAILABLE.

|
|
|
This extension is only available on particular CPUs. It does imply
|
|
AVX, but it is not implied by extensions newer than SSE3. For example,
|
|
AVX2 does not imply it.
