Add new "style" check to catch redundant pointer operations

Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".
The new check is fully AST based and was given
strong false positive testing on a large code base.
