Stas Cymbalov ff38cc5c13 Set struct size cutoff in passedByValue check to 2*sizeof_pointer
Struct arguments are either pushed to the stack or passed in the
registers. Since both methods operate on machine words it is logical to
tie the maximum size of a struct argument that doesn't trigger
passedByValue diagnostic to the size of the machine word.

Also guessed size of STL classes is set to 3*sizeof_pointer, this better
represents reality and ensures that structs containing them will still
trigger passedByValue.

Matthias Krüger aa3f1db33c Add internal check that checks for redundant non-nullness checks in Token::(simple)Match checks.
In code like
if (tok && Token::simpleMatch(tok, "bla")) {}
or
if (tok->previous() && Token::Match(tok->previous(), "foo")) {},
the first check is redundant because Token::(simple)Match already checks if the argument token is null.
