- switched some (TODO) tests to new check if the TODO is fixed

Thomas Jarosch ec21134817 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.

Thomas Jarosch 58cb6cc116 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.

Thomas Jarosch 1cc85bfce3 Add bounds check to getVariableFromVarId()
While poking around the memory leak check,
I managed to trigger an out-of-bounds access
in the symbol database.

Fix it by sanity checking the variable id
passed to getVariableFromVarId().

Thomas Jarosch dca65ce3da Fix FP if sizeof is used without parentheses on struct members
Right now we only support checking basic pointer types.
Pointers inside structs are not supported yet.

Consider the tokens "foo@1 . bar@2",
Token::Match( "sizeof ( %varid% )" ) won't match it.
Token::Match( "sizeof %varid%" ) did match it -> FP.
