SanitizerCommon.PthreadDestructorIterations currently FAILs on Solaris:
[ RUN ] SanitizerCommon.PthreadDestructorIterations
/vol/llvm/src/compiler-rt/local/lib/sanitizer_common/tests/sanitizer_posix_test.cc:58: Failure
Value of: destructor_executed
Actual: true
Expected: false
[ FAILED ] SanitizerCommon.PthreadDestructorIterations (1 ms)
It turns out that destructor is called 4 times after the first call to SpawnThread, but
5 times after the second. While PTHREAD_DESTRUCTOR_ITERATIONS is 4 in
<limits.h>, the Solaris pthread_key_create(3C) man page documents
If, after all the destructors have been called for all keys with non-
null values, there are still some keys with non-null values, the
process will be repeated. POSIX requires that this process be executed
at least PTHREAD_DESTRUCTOR_ITERATIONS times. Solaris calls the
destructors repeatedly until all values with associated destructors are
NULL. Destructors that set new values can cause an infinite loop.
The patch adjusts the test case to allow for this.
Tested on x86_64-pc-solaris2.11.

Like r367463, but for tsan/{benchmarks,dd,go}.
The files benchmarks aren't referenced in the build anywhere and where added
in 2012 with the comment "no Makefiles yet".

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $(basename $f) . ; done
and manually updated references to renamed files found by that.

compiler-rt's builtin library has generic implementations of many
functions, and then per-arch optimized implementations of some.
In the CMake build, both filter_builtin_sources() and an explicit loop
at the end of the build file (see D37166) filter out the generic
versions if a per-arch file is present.
The GN build wasn't doing this filtering. Just do the filtering manually
and explicitly, instead of being clever.
While here, also remove files from the mingw/arm build that are
redundantly listed after D39938 / r318139 (both from the CMake and the
GN build).
While here, also fix a target_os -> target_cpu typo.

Summary:
MSAN was broken on FreeBSD by https://reviews.llvm.org/D55703: after this
change accesses to the key variable call __tls_get_addr, which is
intercepted. The interceptor then calls GetCurrentThread which calls
MsanTSDGet which again calls __tls_get_addr, etc...
Using the default implementation in the SANITIZER_FREEBSD case fixes MSAN
for me.
I then applied the same change to ASAN (introduced in https://reviews.llvm.org/D55596)
but that did not work yet. In the ASAN case, we get infinite recursion
again during initialization, this time because calling pthread_key_create() early on
results in infinite recursion. pthread_key_create() calls sysctlbyname()
which is intercepted but COMMON_INTERCEPTOR_NOTHING_IS_INITIALIZED returns
true, so the interceptor calls internal_sysctlbyname() which then ends up
calling the interceptor again. I fixed this issue by using dlsym() to get
the libc version of sysctlbyname() instead.
This fixes https://llvm.org/PR40761

This option disables the validation of binary UUIDs. This is useful
in environments where the `otool` binary is not available.

Two SPARC builtins tests are currently FAILing due to codegen bugs:
Builtins-sparc-sunos :: divtc3_test.c
Builtins-sparcv9-sunos :: compiler_rt_logbl_test.c
Builtins-sparcv9-sunos :: divtc3_test.c
I'd like to XFAIL them to reduce testsuite noise.
Done as follows, tested on sparcv9-sun-solaris2.11 and x86_64-pc-solaris2.11.

AddressSanitizer-*-sunos :: TestCases/intercept-rethrow-exception.cc currently FAILs
on Solaris. This happens because std::rethrow_exception cannot be intercepted, as
detailed in Bug 42703.
To account for this and reduce testsuite noise, this patch XFAILs the test.
Tested on x86_64-pc-solaris2.11.

Second attempt.
Haven't found a better way to pass the libcxx include path for building
compiler-rt with libcxx; this seems to be missing only for xray.
