1ac922501d Expose symbols in lib/libclang_rt/profile to fix --coverage 
The symbols currently hidden in libprofile_rt are needed for linking with
`clang --coverage` to add coverage counters at link time and produce
coverage numbers at runtime.

9c27ec33f2 Merge compiler-rt release_38 branch r258968. 
Note that there is still a problem on amd64, causing SIGBUS in the early
startup of Address Sanitizer.  This is being investigated.

fe1ef27d4a META MODE: Update dependencies with 'the-lot' and add missing directories. 
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

d07708df70 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.

cfd5b20c8b 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.
