Andreas Pokorny b802b98136 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

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.
