a060f1416a Support compiling lib/libclang_rt/profile a bit more with recent versions of gcc 
Several of the flags were being treated as CFLAGS, when they were actually
technically CXXFLAGS. Move them there.

Only apply -fno-sanitize=safe-stack with clang.

8641eed228 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.

f8ca070d3a 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.

91d03e2e18 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.
