[RFC][StaticAnalyzer] Increased constness for ExplodedNode pointers

[Daniel Marjamäki]

Hello!

This is a request for comments for using 'const' on ExplodedNode pointers.

There are similar code in many checkers and these pointers are rarelly const.

I see no compiler warnings when I apply this patch..

Regards,
Daniel Marjamäki
