Arrays of incomplete arrays should be forbidden

[Halalaluyafail3]

cdecl+ Input

int x[][]

Expected Prose

Can not create array of incomplete arrays

Actual Prose or Error

Declare x as array of arrays of int

Additional Context

This defines the constraints on forming array types:

U is called the array element type; this type shall not be a reference type, a function type, an array of unknown bound, or cv void.

(emphasis mine)

Confirmed. There should be an error diagnostic for that case. I don't think the prose needs to be touched.
