We're using an old NDK and a new Clang. New Clangs default to
`-stdlib=libc++` for Android, but those libraries cannot be found by
default with an old NDK. Use an explicit `-stdlib=libstdc++` in the
cxx_mode_flags.

Summary:
Windows has always been LLP64, not LP64, so the macros were incorrect.
Check for _WIN64, since AArch64 sets that too.
The tests have to be fixed up in two main ways:
1. Use 'ULL' suffixes to avoid sign extension when passing hex literals
with the sign bit set to signed 128 arguments. Clang
-fms-compatibility makes such hex literals signed, not unsigned.
2. Disable various tests for 80-bit long double interoperation with i128
values.

Summary:
In r81552, the HAS_80_BIT_LONG_DOUBLE macro was added to the unit test
only version of int_lib.h. One month later in r85260 the duplicate
int_lib.h was removed, but the tests still passed because we don't build
with -Werror.
This is the minimal change to bring it back, and I decided to put the
configuration macro next to our 128-bit integer support macro.

Revert older change that was incorrect in this test.
It was already reverted in the past after an attempt to port it to Darwin.
While there, mark FreeBSD as unsupported as well.
llvm-svn: 345492
Summary:
The previous value looks Linux specific so that has been guarded with
the host OS being Linux.
On Apple platforms `%shared_libasan` expands to the absolute path of the
ASan dylib.
Previously on Linux `%shared_libasan` expanded to just the file name
of the shared library rather than the absolute path to the library.
This is likely a bug because it would rely on the OS's dynamic linker
to find the shared library which could accidentally pick up a system copy
rather than the shared library that was just built.
For other platforms we emit a warning if `config.asan_dynamic` is true.
This patch also only defines the substitution when `config.asan_dynamic`
is true because using this substitution only makes sense when the
dynamic library is available.

Summary:
Linking with the /OPT:REF linker flag when building COFF files causes
the linker to strip SanitizerCoverage's constructors. Prevent this by
giving the constructors WeakODR linkage and by passing the linker a
directive to include sancov.module_ctor.
Include a test in compiler-rt to verify libFuzzer can be linked using
/OPT:REF

`config.asan_dynamic` should actually be `True` because dylibs are the
only supported form of the ASan runtime on Apple platforms.

PTHREAD_STACK_MIN is not available on NetBSD as it's not
clear what the value shall be represented by this constant
on a multiplatform OS.

Summary:
The dl library does not exist on all system and in particular
this breaks build on NetBSD. Make it conditional and
enable only for Linux, following the approach from other
test suites in the same repository.

NetBSD returns a different type as a return value of
devname_r(3) than FreeBSD and Darwin (int vs char*).
This implies that checking for successful completion of this
function has to be handled differently.
This test used to work well, but was switched to fix Darwin,
which broke NetBSD.
Add a dedicated ifdef for NetBSD and make it functional again
for this OS.

In long-running builds we've seen some ASan complaints during thread creation that we suspect are due to leftover poisoning from previous threads whose stacks occupied that memory. This patch adds a hook that unpoisons the stack just before the NtTerminateThread syscall.
