d18cb502bd use EP_OptimizerLast instead of EP_ScalarOptimizerLate for ThreadSanitizer

28a7a1198b Add a flag -fthread-sanitizer. 
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423.
The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer.
This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet
committed and it's structure in compiler-rt is not 100% clear.
The users manual wil be changed in a separate commit.

b1cfc6864f Allocate TargetLibraryInfo for the CodeGen passes. Otherwise, it's instantiated 
by the BAA pass, which uses the default TargetLibraryInfo constructor.
Unfortunately, the default TargetLibraryInfo constructor assumes all library
calls are available and thus ignores -fno-builtin.

14adb360a7 Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325> 
That llvm change removed the -trap-func backend option, so that using
-ftrap-function with clang would cause the backend to complain.  Fix it
by adding the trap function name to the CodeGenOptions and passing it through
to the TargetOptions.

207bce31e1 Wire up the -ftest-coverage and -fprofile-arcs flags to .gcno file emission (at 
compile time) and .gcda emission (at runtime). --coverage enables both.

This does not yet add the profile_rt library to the link step if -fprofile-arcs
is enabled when linking.

15e36e8edd Added *hidden* flags -print-options and -print-all-options so 
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.

Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.

12100e2c7f Frontend: Add a more explicit -backend-option flag for passing backend command 
line options, instead of leveraging the blanket -mllvm option.
 - This allows using the frontend itself without requiring the backend have
   those options available (i.e., if the target wasn't built).
