This flag suppresses TSan FPs on Darwin. I removed this flag
prematurely and have been dealing with the fallout ever since.
This commit puts back the flag, reverting 7d1085cb [1].

Summary:
A number of testcases in TSAN are designed to deal with intermittent problems
not exist in all executions of the tested program. A script called deflake.bash
runs the executable up to 10 times to deal with the intermittent nature of the tests.
The purpose of this patch is to parameterize the hard-coded threshold above via
--cmake_variables=-DTSAN_TEST_DEFLAKE_THRESHOLD=SomeIntegerValue
When this cmake var is not set, the default value of 10 will be used.

Use a new %run wrapper for ASAN/MSAN/TSAN tests that calls paxctl
in order to disable ASLR on the test executables. This makes it
possible to test sanitizers on systems where ASLR is enabled by default.

These lit configuration files are really Python source code. Using the
.py file extension helps editors and tools use the correct language
mode. LLVM and Clang already use this convention for lit configuration,
this change simply applies it to all of compiler-rt.
