Vedant Kumar 2b588cbf15 Low-hanging fruit optimization in string::__move_assign().

shrink_to_fit() ends up doing a lot work to get information that we
already know since we just called clear(). This change seems concise
enough to be worth the couple extra lines and my benchmarks show that it
is indeed a pretty decent win. It looks like the same thing is going on
twice in __copy_assign_alloc(), but I didn't want to go overboard since
this is my first contribution to llvm/libc++.

libc++ Documentation
====================

The libc++ documentation is written using the Sphinx documentation generator. It is
currently tested with Sphinx 1.1.3.

To build the documents into html configure libc++ with the following cmake options:

  * -DLLVM_ENABLE_SPHINX=ON
  * -DLIBCXX_INCLUDE_DOCS=ON

After configuring libc++ with these options the make rule `docs-libcxx-html`
should be available.
