- Rename WasmTrapElemSegmentDropped -> WasmTrapElemSegmentOutOfBounds.
- Rename WasmArrayInitFromData -> WasmArrayInitFromSegment, in
  anticipation of array.init_from_elem.
- Rename InitExprInterface::result_ -> computed_value_, to
  distinguish it from the {result} values. Also, rename
  generate_result() -> generate_value().
- Drive-by: Restructure Runtime_WasmArrayInitFromSegment.
