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.

5c238692e6 New check: Division by sizeof() as parameter to memset/memcpy/memmove/etc. as they expect a size in bytes (#5698) 
Refactorizations in sizeof checking:
- Changed severity of sizeofwithsilentarraypointer to warning
- Made pointerSize message conclusive - there seems to be no reason for inconclusive
