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.
