Dave Zarzycki showed how the efficiency of shared_ptr could be significantly
increased. The following program is running 49% faster:
#include <iostream>
#include <memory>
#include <chrono>
#include <vector>
#include "chrono_io"
int main()
{
typedef std::chrono::high_resolution_clock Clock;
Clock::time_point t0 = Clock::now();
{
std::shared_ptr<int> p(new int (1));
std::vector<std::shared_ptr<int> > v(1000000, p);
v.insert(v.begin(), p);
v.insert(v.begin(), p);
v.insert(v.begin(), p);
v.insert(v.begin(), p);
}
Clock::time_point t1 = Clock::now();
std::cout << (t1-t0) << '\n';
}

I am experimenting with putting visibility-default attributes on all struct/classes in libc++. This checkin decorates only basic_string and vector as an experiment, and for review by those in this audience that might know more about visibilty than I do. If I get no negative feedback on this procedure I will begin to decorate the entire library in this way.

Changed __config to react to all of clang's currently documented has_feature flags, and renamed _LIBCPP_MOVE to _LIBCPP_HAS_NO_RVALUE_REFERENCES to be more consistent with the rest of the libc++'s flags, and with clang's nomenclature.

[rand.dist.bern.bin]. The evaluation function for this binomial distribution is hopefully just a placeholder. It is using the simplest and slowest method for computing the distribution and needs to be upgraded.
