Summary:
Original patch by Kuba Mracek
The %T lit expansion expands to a common directory shared between all
the tests in the same directory, which is unexpected and unintuitive,
and more importantly, it's been a source of subtle race conditions and
flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it
would be best to simply ban %T and only keep %t, which is unique to each
test. When a test needs a temporary directory, it can just create one
using mkdir %t.
This patch removes %T in compiler-rt.

We already have %env_asan_opts for ASan, let's implement the same for TSan.

This patch adds support for tsan on aarch64-linux with 42-bit VMA
(current default config for 64K pagesize kernels). The support is
enabled by defining the SANITIZER_AARCH64_VMA to 42 at build time
for both clang/llvm and compiler-rt. The default VMA is 39 bits.
It also enabled tsan for previous supported VMA (39).

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.

Summary:
Always quote suppressions files given to *_OPTIONS.
This will make it not break when given full Windows paths (otherwise,
parsing would stop after the drive's letter + ':').
Also fix one or two cases where the suppression files' extensions were
not *.supp.

Add a script that is used to deflake inherently flaky tsan tests.
It is invoked from lit tests as:
%deflake %run %t
The script runs the target program up to 10 times,
until it produces a tsan warning.
