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).

This patch adds 48-bits VMA support for msan on aarch64. As current
mappings for aarch64, 48-bit VMA also supports PIE executable. The
48-bits segments only cover the usual PIE/default segments plus some
more segments (262144GB total, 0.39% total VMA). Memory avaliability
can be increase by adding multiple application segments like 39 and
42 mapping (some mappings were added on this patch as well).
Tested on 39 and 48-bit VMA kernels on aarch64.

These tests were recently enabled and have never worked on this builder.
Three tests were sensitive to line number changes:
test/msan/Linux/obstack.cc
test/msan/chained_origin.cc
test/msan/chained_origin_memcpy.cc
and this sensitivity will be addressed in a follow-up patch. Of these,
obstack.cc's sensitivity to line numbers is unexplained since it already uses
[[@LINE]].

Adding the XFAIL has caused msan to report a different line number in the call
stack (@LINE-3 rather than @LINE-30). The new line number looks more correct
at first glance since it's the line that uses uninitialized memory rather than
the first non-whitespace line of the file but this needs investigating.

The mips64el compiler-rt build has recently been enabled. XFAIL the failing
tests to make the buildbot green again.
The two asan tests require the integrated assembler. This will be fixed soon
for Debian mips64el but not for any other mips64el targets since doing so
requires triple-related issues to be fixed..
The msan tests are largely failing because caused by a kernel update (a patch
has already been posted for this).
I'm not sure why the dfsan test fails yet.

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

Dstaddr may contain uninitialized padding at the end (common
implementations accept larger addrlen and ignore the extra bytes).
Also, depending on the socket state, dstaddr argument may be ignored.

This fixes fails in test/msan/dlerror.cc - when real dlerror calls strcmp,
our strcmp interceptor now skips poison checking, since it's called in
interceptor context. Strictly speaking, only the dlerror change is
necessary to fix the fail, but let's also change the other two just in case.

At the moment almost every lit.site.cfg.in contains two lines comment:

configure_lit_site_cfg with the note and some useful information.

Summary: This is an initial setup in order to move some additional tests from Linux onto Posix.
I also moved decorate_proc_maps onto the Linux directory
Finally added msan's definition for "stable-runtime".
Only a test requires it, and its commit message (r248014) seems to imply
that AArch64 is problematic with MSan.

Summary: As per the test the 4th element of both arrays are not initialized and hence will contain garbage values. Memcmp returns the difference between the garbage values of the 4th element which will be different on every run of the test. And since the return value of memcmp is returned from main, we are getting random exit code every time.

Test cases definitely should not care about the complete set of architectures
supported by compiler-rt - they should only care about current
architecture that the test suite was configured for.
Introduce new lit feature to reflect this, and convert tests to use it.

There's no obvious reason it should fail in this way but it's the only change
on the blamelist. I suspect stale lit*.cfg's from previous builds.

The lit test-suite containing the unit tests needs to be explicitly specified
as an argument to lit.py since it is no longer discovered when the other tests
are run (because they are one directory deeper).
dfsan, lsan, and sanitizer_common don't show the same problem.
