Attached is a patch to add support for array_length(anyarray), which

Why the heck would it complain if the lower bound isn't 1?
Because then you're free to assume that the first element is [1] and the
last one is [array_length()]. Which is what 99% of the code using
array_length(anyarray, int) does anyway.
