Upgrade our copies of clang, llvm, lldb, compiler-rt and libc++ to 3.7.0
release.

Please note that from 3.5.0 onwards, clang, llvm and lldb require C++11
support to build; see UPDATING for more information.

Release notes for llvm and clang can be found here:
<http://llvm.org/releases/3.7.0/docs/ReleaseNotes.html>
<http://llvm.org/releases/3.7.0/tools/clang/docs/ReleaseNotes.html>

Thanks to Ed Maste, Andrew Turner and Antoine Brodin for their help.

Update compiler-rt to 3.7.0 release. This also includes the sanitizer
and profile libraries.

Create a branch for working on the clang/llvm/lldb 3.7.0 import.

(Copied from projects/clang-trunk, since that is now at the last
revision before upstream branched off 3.7.0.)

Create project branch for doing clang/lld/lldb/llvm trunk imports.

Now compiler-rt has been updated in r276851, bring in the various
sanitizer libraries that already work on FreeBSD:

* asan: Address Sanitizer
* ubsan: Undefined Behavior Sanitizer
* profile: Profile Guided Optimization support

Please note that these libraries are *experimental* at this stage, so
the main Makefile is not yet connected to the build.

Since I didn't want to needlessly edit BSD.usr.dist, you will also have
to create the install directory /usr/lib/clang/3.5.0/lib/freebsd
manually for now.
