Typedef rewriting error for arrays

[john-h-kastner]

typedef int foo [10];
foo bar;

Is rewritten to (-alltypes)

typedef int _Checked[10] foo;
foo bar;

That was an easy one: #441.

This was fixed by #408. We don't have a regression test specifically for arrays, but function_typedef.c exercises the same code path for function types, so I'm going to call that good enough.
