Connect libclang_rt to the build, for specific architectures. This

contains the libraries for Address Sanitizer (asan), Undefined Behavior
Sanitizer (ubsan) and Profile Guided Optimization.

ASan is a fast memory error detector. It can detect the following types
of bugs:

    Out-of-bounds accesses to heap, stack and globals
    Use-after-free
    Use-after-return (to some extent)
    Double-free, invalid free
    Memory leaks (experimental)

Typical slowdown introduced by AddressSanitizer is 2x.

UBSan is a fast and compatible undefined behavior checker. It enables a
number of undefined behavior checks that have small runtime cost and no
impact on address space layout or ABI.

PLEASE NOTE: the sanitizers still have some rough edges on FreeBSD,
particularly on i386.  These will hopefully be smoothed out in the
coming time.

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.
