commit 8311c83f91a3127ccd2fe684e25bc60c5178d23b

array_length: Make usable as a constant expression
Do not use a statement expression in array_length, so that
array_length can be used at file scope and as a constant expression.
Instead, put the _Static_assert into a struct (as a declaration),
and nest this in the expression using a sizeof expression.
