#[target_feature(enable = "fma")]
pub const fn _mm_fnmsub_ss(a: __m128, b: __m128, c: __m128) -> __m128Multiplies the lower single-precision (32-bit) floating-point elements in
a and b, and subtract packed elements in c from the negated
intermediate result. Store the result in the lower element of the
returned value, and copy the 3 upper elements from a to the upper
elements of the result.
