textdomain is a part of -lintl on BSDs. In GLIBC it's in libc.
We assume that -lintl will need to be rebuilt with sanitizers
in order to sanitize programs using its features.
This is a proper continuation of D41013.
The original patch has been reverted (adding -lintl).

Summary:
Enable the compile-time flag -fsanitize-memory-use-after-dtor by
default. Note that the run-time option MSAN_OPTIONS=poison_in_dtor=1
still needs to be enabled for destructors to be poisoned.

Summary:
Changes:
* Add initial msan stub support.
* Handle NetBSD specific pthread_setname_np(3).
* NetBSD supports __attribute__((tls_model("initial-exec"))),
define it in SANITIZER_TLS_INITIAL_EXEC_ATTRIBUTE.
* Add ReExec() specific bits for NetBSD.
* Simplify code and add syscall64 and syscall_ptr for !NetBSD.
* Correct bunch of syscall wrappers for NetBSD.
* Disable test/tsan/map32bit on NetBSD as not applicable.
* Port test/tsan/strerror_r to a POSIX-compliant OSes.
* Disable __libc_stack_end on NetBSD.
* Disable ReadNullSepFileToArray() on NetBSD.
* Define struct_ElfW_Phdr_sz, detected missing symbol by msan.
* Change type of __sanitizer_FILE from void to char. This helps
to reuse this type as an array. Long term it will be properly
implemented along with SANITIZER_HAS_STRUCT_FILE setting to 1.
* Add initial NetBSD support in lib/tsan/go/buildgo.sh.
* Correct referencing stdout and stderr in tsan_interceptors.cc
on NetBSD.
* Document NetBSD x86_64 specific virtual memory layout in
tsan_platform.h.
* Port tests/rtl/tsan_test_util_posix.cc to NetBSD.
* Enable NetBSD tests in test/msan/lit.cfg.
* Enable NetBSD tests in test/tsan/lit.cfg.

This is a very poorly named feature. I think originally it meant to cover linux only, but the use of it in msan
seems to be about any aarch64 platform. Anyway, this change should be NFC on everything except Android.

Summary:
Check sigset_t arguments in ppoll, sig*wait*, sigprocmask
interceptors, and the entire "struct sigaction" in sigaction. This
can be done because sigemptyset/sigfullset are intercepted and
signal masks should be correctly marked as initialized.

The test was not passing on targets where allocator_may_return_null

Summary:
ASan/MSan/LSan allocators set errno on allocation failures according to
malloc/calloc/etc. expected behavior.
MSan allocator was refactored a bit to make its structure more similar
with other allocators.
Also switch Scudo allocator to the internal errno definitions.
TSan allocator changes will follow.

Summary:
Operator new interceptors behavior is now controlled by their nothrow
property as well as by allocator_may_return_null flag value:
- allocator_may_return_null=* + new() - die on allocation error
- allocator_may_return_null=0 + new(nothrow) - die on allocation error
- allocator_may_return_null=1 + new(nothrow) - return null
Ideally new() should throw std::bad_alloc exception, but that is not
trivial to achieve, hence TODO.

GNU version of strerror_r returns a result pointer that doesn't match the input
buffer. The result pointer is in fact a pointer to some internal storage.
TSAN was recording a write to this location, which was incorrect.

Summary: For platforms which support slow unwinder only, we restrict the store context size to 1, basically only storing the current pc. We do this because the slow unwinder which is based on libunwind is not async signal safe and causes random freezes in forking applications as well as in signal handlers.

The Clang driver on macOS decides the deployment target based on various things, like your host OS version, the SDK version and some environment variables, which makes lit tests pass or fail based on your environment. Let's make sure we run all lit tests with `-mmacosx-version-min=${SANITIZER_MIN_OSX_VERSION}` (10.9 unless overriden).
