Fix false negatives for local suppressions
...
Introduce a new bool setting jointSuppressionReport
that will be set by the analyseWholeProgram() code path.
When the flag is enabled, unmatched suppressions are
collected after running the final whole program analysis
to prevent false positives for the unusedFunction check.
The check functions in the unit test
for single / multi file suppressions were unified.

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.
