Bill Schmidt 2979162732 [PPC64, TSAN] LLVM basic enablement of thread sanitizer for PPC64 (BE and LE)
This patch is by Simone Atzeni with portions by Adhemerval Zanella.

This contains the LLVM patches to enable the thread sanitizer for
PPC64, both big- and little-endian.  Two different virtual memory
sizes are supported:  Old kernels use a 44-bit address space, while
newer kernels require a 46-bit address space.

There are two companion patches that will be added shortly.  There is
a Clang patch to actually turn on the use of the thread sanitizer for
PPC64.  There is also a patch that I wrote to provide interceptor
support for setjmp/longjmp on PPC64.

Patch discussion at reviews.llvm.org/D12841.

Kuba Brecka f642e88342 [tsan] Use MAP_ANON instead of MAP_ANONYMOUS
In mmap_large.cc, let's use MAP_ANON instead of MAP_ANONYMOUS, because MAP_ANONYMOUS is only available on OS X 10.11 and later.

Adhemerval Zanella d7984710ae [tsan] Enable tsan for aarch64
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.

Dmitry Vyukov 362d1202e2 tsan: fix test
this test is flaky because of ASLR
app memory is 7e8000000000-800000000000,
there may or may not be a 1TB hole depending on
where ASLR will choose to map libraries

Dmitry Vyukov b1edac069e tsan: more precise check for "app memory" in COMPAT mode
this fires when a user makes mmap with fixed address (see the test)
