InstrProf: XFAIL tests from r208940 on Linux
...
According to the buildbots, the new features for shared objects don't
work on ELF since it requires an -fPIC when building the profile
library. XFAIL these tests for now.
It's possible we'll have to build two versions of the profile library on
Linux (one with -fPIC and one without), but it's not clear to me exactly
how to resolve this.

InstrProf: Fix shared object profiling
...
Change the API of the instrumented profiling library to work with shared
objects.
- Most things are now declared hidden, so that each executable gets
its own copy.
- Initialization hooks up a linked list of writers.
- The raw format with shared objects that are profiled consists of a
concatenated series of profiles. llvm-profdata knows how to deal
with that since r208938.

[TSan] Build TSan-instrumented version of libcxx and use it in lit tests.
...
TSan can produce false positives in code that uses C++11 threading,
as it doesn't see synchronization inside standard library. See
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-February/035408.html
for an example of such case.
We may build custom TSan-instrumented version libcxx to fight with that.
This change adds build rules for libcxx_tsan and integrates it into
testing infrastructure.

[ASan] Fix coverage behavior when a PC belongs to an unknown address range.
...
This happens, e.g., when coverage data is collected for a module which is then
dlclose()'d. Currently this causes CovDump() to ignore all PCs that are greater
than the unrecognized PC. In other words, unloading a module causes ASan to
silently ignore any coverage data for modules loaded at higher addresses.
Instead we should just skip the unrecognized PCs.

[CMake] Add the way to run tests in standalone build.
...
1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to
get necessary LLVM source/binary directories.
2) Add basic support for running lit tests (check-xsan commands).
For now this "support" is far from what we want:
* unit tests are not built currently.
* lit tests use Clang/compiler-rt from LLVM build directory,
not the host compiler or just-built compiler-rt libraries.
We should make a choice on the way we intend ti run compiler-rt lit testsuite:
a) use either Clang from LLVM build tree, or the host compiler.
b) use either just-built runtimes, or the runtimes shipped with the
host compiler.
Using just-built runtimes is tricky - we have to know where to put them, so that
Clang/GCC driver would pick them up (and not overwrite the existing runtimes).
Using a host compiler instead of Clang from LLVM build tree will give us a chance to
run lit tests under GCC (which already has support for several sanitizers).
That is, I tend to make the following choice: if we're in a standalone compiler-rt
build, use host compiler with its set of runtime libraries to run lit tests.
This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in
a standalone build - the latter wouldn't invoke the former. Note that if we decide
to fix LLVM/Clang/compiler-rt build system so that it would configure/build
compiler-rt with just-built Clang (as we do in Makefile-based build), this will not
be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt
before running compiler-rt tests.

Remove the old, and non-functional CMake build system from CompilerRT.
...
I cannot build any part of this successfully on either Linux or Darwin,
and the replacement is worlds simpler by requiring that this be built as
a subproject of LLVM. If this breaks you for any reason, please let me
know, and let me know what your use case is.

Add support for "platform" configurations, which define a suite of compiler-rt

libraries to generate.
- Each library may be built with different flags and for different
architectures, and there is support for building Darwin style fat archives.
- Uses an ambituous amount of make programming, but should be hidden to
users and developers.
