Remove unnecessary null pointer checks

[elfring]

An extra null pointer check is not needed in functions like the following.

• cAnalyzeView
• cCPUTestInfo
• cLandscape
• cView

How do you think about to improve the affected source code?

I agree completely with the removal of the null checks. At the time I originally wrote this code, I hadn't realized that it was safe to delete null pointers (or rather, that delete always performs this check).
