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.

compunit's .data section. This vector is not poisoned. Because of this the
first symbol of the following section has no left red zone. As a result, ASan
cannot detect underflow for such symbols.
Poison ASan allocated metadata, it should not be accessible to user code.
This fix does not eliminate the problem with missing left red zones but it
reduces the set of vulnerable symbols from first symbols in each input data
section to first symbols in the output section of the binary.

Keeping tests isolated to a single file is nice, and it was suggested in
post-commit review for r244827.

Revise the fix to https://code.google.com/p/address-sanitizer/issues/detail?id=178:
always disable strict init-order checking the first time dlopen() is
called: at this point shared library is allowed to access globals
defined in the main executable, as they are guaranteed to be
initialized. Revise the test cases:
* simplify init-order-dlopen.cc test case: make it Linux-specific
(there's no strict init-order checking on other platforms anyway),
and single-threaded.
* reinforce init-order-pthread-create.cc test case: make sure that
init-order checker would produce a false positive unless we
turn it off at the moment we call pthread_create().
