These test cases occassionally fail when run on powerpc64le:
ignore_lib1.cc
ignore_lib5.cc
TestCases/Posix/current_allocated_bytes.cc
rtl/TsanRtlTest/Posix.ThreadLocalAccesses
TestCases/Posix/coverage-fork-direct.cc
The failures cause false problem reports to be sent to developers whose
code had nothing to do with the failures. Reactivate them when the real
problems are fixed.
This could also be related to the same problems as with the tests
ThreadedOneSizeMallocStressTest, ThreadedMallocStressTest, ManyThreadsTest,
and several others that do not run reliably on powerpc.

On Darwin, we're running the TSan unit tests without interceptors. To make sure TSan observes all the pthread events (thread creating, thread join, condvar signal, etc.) in tsan_posix.cc, we should call the pthread interceptors directly, as we already do in tsan_test_util_posix.cc. This fixes some flaky failures on Darwin bots.

On OS X, this unit test (ThreadSpecificDtors) fails, because the new and delete operators actually call the overridden operators, which end up using TLVs and crash. Since C++'s new and delete is not important in this test, let's just replace them with a local variable. This fixes the test on OS X.

This patch enabled TSAN for aarch64 with 39-bit VMA layout. As defined by
tsan_platform.h the layout used is:
0000 4000 00 - 0200 0000 00: main binary
2000 0000 00 - 4000 0000 00: shadow memory
4000 0000 00 - 5000 0000 00: metainfo
5000 0000 00 - 6000 0000 00: -
6000 0000 00 - 6200 0000 00: traces
6200 0000 00 - 7d00 0000 00: -
7d00 0000 00 - 7e00 0000 00: heap
7e00 0000 00 - 7fff ffff ff: modules and main thread stack
Which gives it about 8GB for main binary, 4GB for heap and 8GB for
modules and main thread stack.
Most of tests are passing, with the exception of:
* ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for
no support to make mmap page non-executable.
* longjmp tests due missing specialized assembly routines.
These tests are xfail for now.
The only tsan issue still showing is:
rtl/TsanRtlTest/Posix.ThreadLocalAccesses
Which still required further investigation. The test is disable for
aarch64 for now.
