Function f32x4
#[target_feature(enable = "simd128")]
pub const fn f32x4(a0: f32, a1: f32, a2: f32, a3: f32) -> v128
Materializes a SIMD value from the provided operands.
If possible this will generate a v128.const instruction, otherwise it may
be lowered to a sequence of instructions to materialize the vector value.
