I ran the test suite yesterday and when I came back this morning the
queue_user_work_item.cc test was hung. This could be why the
sanitizer-windows buildbot keeps randomly timing out. I updated all the
usages of WaitForSingleObject involving threading events. I'm assuming
the API can reliably wait for subprocesses, which is what the majority
of call sites use it for.
While I'm at it, we can simplify some EH tests now that clang can
compile C++ EH.

Compiler-rt only relies on LLVM for lit support. Pushing this dependency down into the test and unitest layers will allow builtin libraries to be built without LLVM.

1. Add two explicit -stdlib=libstdc++ in conjunction with -static-libstdc++
2. Pass -nostdinc++ when adding include paths for libc++ built for tsan. This
prevents clang finding the headers twice which would confuse #include_next

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.

Summary:
In some cases stack pointer register (SP) doesn't point into the thread
stack: e.g. if one is using swapcontext(). In this case LSan
conservatively tries to scan the whole thread stack for pointers.
However, thread stack (at least in glibc implementation) may also
include guard pages, causing LSan to crash when it's reading from them.
One of the solutions is to use a pthread_attr_getguardsize() to adjust
the calculated stack boundaries. However, here we're just using
IsAccessibleMemoryRange to skip guard pages and make the code (slightly)
less platform-specific.

This test isn't posix specific, but it doesn't pass on Windows and is
XFAILed. I suspect that this test, which is expected to fail, is causing
the hangs I'm seeing on our WinASan builder. Moving it to Posix seems
to be the cleanest way to avoid running it on Windows.

Summary:
Previously, the tests only ran for the 64-bit equivalent of the default target
(see -m64).
Given the supported architecture list only contains 64-bit targets, this happens
to work out the same as the supported targets in most cases but may matter for
X86_64/X86_64h on Darwin.
For other targets, the practical effect is that the test names contain the
architecture. This resolves some confusion when lsan tests fail since their
name no longer implies that they are trying to test the default target.

This fixes duplicate test names in the test results, so:

is now:

This is a compiler-rt part of this http://reviews.llvm.org/D15642 patch. Here,
we add a new approach for ODR violation detection.
Instead of using __asan_region_is_poisoned(g->beg, g->size_with_redzone) on
global address (that would return false now due to using private alias), we can
use new globally visible indicator symbol to perform the check.
