Import libc++ trunk r165949. Among other improvements and bug fixes,

this has many visibility problems fixed, which should help with
compiling certain ports that exercise C++11 mode (i.e. Firefox).

Also, belatedly add the LICENSE.TXT and accompanying CREDITS.TXT files,
which are referred to in all the source files.
