Do not warn when unique pointers are passed by value

A unique pointer should only be passed by value or by const reference.
Passing by value means transferring ownership it makes no sense to have a pass by value Warning for unique_ptr

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.
