Delete NULL test on array. The complete semantic patch that finds this
problem is as follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
type T;
T [] e;
position p;
@@

(
e ==@p NULL
|
e !=@p NULL
|
!@p e
)

@ disable fld_to_ptr@
expression e;
identifier f;
position r.p;
@@

(
* (e.f) ==@p NULL
|
* (e.f) !=@p NULL
|
* !@p(e.f)
)
// </smpl>

For best results, this semantic patch requires lots of type information,
and should be used with the options --recursive-includes and
--relax-include-path. This may take a long time to run.
