  -----------
  [AArch64][GlobalISel] Add fp128 and i128 fptosi/fptoui handling. (#95528)

Any fp128 need to end up as libcall, as will f32->i128 and f64->i128.
f16 are a bit special as the maximum range of the result fits in a i17,
so can be shrank to an i64. Vector with i128/fp128 types are scalarized.
