Function _mm_loadh_pd
#[target_feature(enable = "sse2")]
pub const unsafe fn _mm_loadh_pd(a: __m128d, mem_addr: *const f64) -> __m128dLoads a double-precision value into the high-order bits of a 128-bit
vector of [2 x double]. The low-order bits are copied from the low-order
bits of the first operand.
