Function i8x16
#[target_feature(enable = "simd128")]
pub const fn i8x16(a0: i8, a1: i8, a2: i8, a3: i8, a4: i8, a5: i8, a6: i8, a7: i8, a8: i8, a9: i8, a10: i8, a11: i8, a12: i8, a13: i8, a14: i8, a15: i8) -> 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.
