Eric Fiselier 1c0cedccb6 [libc++] Fix PR34898 - vector iterator constructors and assign method perform push_back instead of emplace_back.
Summary:
The constructors `vector(Iter, Iter, Alloc = Alloc{})` and `assign(Iter, Iter)` don't correctly perform EmplaceConstruction from the result of dereferencing the iterator. This results in them performing an additional and unneeded copy.

This patch addresses the issue by correctly using `emplace_back` in C++11 and newer.

There are also some bugs in our `insert` implementation, but those will be handled separately. 

@mclow.lists We should probably merge this into 5.1, agreed?
