This allows algebraic optimizations to check if the argument accesses
multiple distinct components of a vector. So a swizzle like "xyz" will
return true, but "yyy" will return false, as will a scalar. This can be
useful for optimizations on vector processors, where a scalar
swizzle can be handled i
