 * Represents the typecasting of an array. Arrays cannot be directly casted in SkSL (or GLSL), but
 * type narrowing can cause an array to be implicitly casted. For instance, the expression
 * `myHalf2Array == float[2](a, b)` should be allowed when narrowing conversions are enabled; this
 * constructor allows the necessary array-type conversion to be represented in IR.
 *
 * These always contain exactly 1 array of matching size, and are never constant.
