There was only one use of COMPLETE_OR_UNBOUND_ARRAY_TYPE_P outside the
frontends, in expr.c.  This patch expands the macro there and moves the
macro's definition to c-common.h.

It feels a bit odd that we still have decls with no layout at
this late stage, but that's a separate issue...

gcc/
	* tree.h (COMPLETE_OR_UNBOUND_ARRAY_TYPE_P): Move to c-common.h.
	* expr.c (expand_expr_real_1): Expand use of
	COMPLETE_OR_UNBOUND_ARRAY_TYPE_P here.

gcc/c-family/
	* c-common.h (COMPLETE_OR_UNBOUND_ARRAY_TYPE_P): New macro,
	moved from tree.h.
