7776	vector::assign(Iter first, Iter last) should be implemented more efficiently	kariya_mitsuru@…	Ion Gaztañaga	"Current implementation of vector::assign(Iter first, Iter last) is same behavior whether Iter is ForwardIterator or not. (First, overwrite to current elements, then erase or insert)

But if Iter is ForwardIterator and capacity() < distance(first, last), it is only necessary to discard old buffer (including its contents) and allocate new buffer which capacity is at least distance(first, last).

Note: according to C++11 specification, value_type need not be MoveInsertable into Container if Iter is ForwardIterator."	Bugs	closed	To Be Determined	container	Boost 1.52.0	Optimization	fixed
