Silence clang static analyzer warning about null dereference

Add a return in addition to the existing check,
otherwise null would be dereferenced.

Silence clang static analyzer warning about possible null deref

In all paths, with a null 'W', these functions could only
do nothing or crash, so just bail early if W is null.

Fixed null dereference

DeepCopy() does SetLookupTable(0), and with a null parameter,
it would dereferenced null.  Fixed by adding null check.
Found by clang static analyzer.

Silence clang static analyzer warning about null deref

Add a return in addition to the existing vtkErrorMacro,
otherwise aa2/null would be dereferenced in the next
'if' statement.

Convince clang static analyzer that null deref will not occur

These classes dereference 'this->Data' in many many places
without ever checking that its null, so I assume it's
basically not possible.  If it were possible to be null, PrintSelf
would already be crashing since it calls other methods that
don't check.

Convince clang analyzer that no uninitialize read occurs

The added assert hints to the compiler that, in the context of
these copy methods, the 'val' array will always be initialized.
