Summary:
I finally got around to merging the many, many changes to lit.cfg into
Android's libc++. This patch makes it simpler to actually use a custom
configuration and test format.
First, I've factored out _build, _run, and _clean methods from
_execute_test, since these are the likely parts that will need to be
overridden. This is likely a first step in the work jroelofs has been
doing with improving cross-compiling test execution.
Second, I've added a `configuration_variant` to the config. This
entry, if present, is a string that forms the prefix of the class that
is to be used to configure the test runner. For example, Android sets
`config.configuration_variant = 'Android'`, and this causes an object
of type `AndroidConfiguration` to be constructed.
As an example of how this will be used, see:

The standard requires that nullptr_t can be reinterpret_cast to an integral type
at least the size of nullptr_t. There is no way to emulate this conversion in
the C++03 nullptr_t implementation. The test for this conversion has been moved
to a new test and marked XFAIL with c++03.
This recommits what was originally r222296.

Wrap the original test in _LIBCPP_HAS_QUICK_EXIT so it only runs when we have
quick_exit and add two new tests that check that when _LIBCPP_HAS_QUICK_EXIT
is not defined then no definition of std::at_quick_exit or std::quick_exit are
available.

The second part of the test checks that std::terminate is called when a running
thread is move assigned to. Calling std::terminate prevents some of the destructors
to be called and ASAN fires on this.

Summary: The strstream function `str()` sets `freeze(true)`. When `freeze` is true the destructor is not allowed to free any dynamically allocated memory. The memory leak causes ASAN to fail on these tests. To ensure memory is deallocated `strstream.freeze(false)` is called at the end of the tests.

The test is split such that:
- max_size.pass.cpp tests that string::resize() fails to allocator for max_size
and max_size -1
- over_max_size.pass.cpp tests that string::resize() throws a length error for
max_size + 1
The test was split into two because max_size.pass.cpp cannot pass with
sanitizers but over_max_size.pass.cpp can.

These tests fail for 2 reasons when using ASAN and MSAN.
1. If allocator_may_return_null=0 they will fail because null is returned
or an exception is thrown.
2. When allocator_may_return_null=1 the new_handler is still not called. This
results in an assertion failures.

tests that replace operator new/delete won't link when using ASAN and MSAN
because these sanitizers also replace new/delete.

Summary:
http://llvm.org/bugs/show_bug.cgi?id=18345
Tuple's constructor and assignment operators for "tuple-like" types evaluates __make_tuple_types unnecessarily. In the case of a large array this can blow the template instantiation depth.
Ex:
```
#include <array>
#include <tuple>
#include <memory>
typedef std::array<int, 1256> array_t;
typedef std::tuple<array_t> tuple_t;
int main() {
array_t a;
tuple_t t(a); // broken
t = a; // broken
// make_shared uses tuple behind the scenes. This bug breaks this code.
std::make_shared<array_t>(a);
}
```
To prevent this from happening we delay the instantiation of `__make_tuple_types` until after we perform the length check. Currently `__make_tuple_types` is instantiated at the same time that the length check .
Test Plan: Two tests have been added. One for the "tuple-like" constructors and another for the "tuple-like" assignment operator.

For targets that end it `redhat-linux` and `suse-linux` manually add the `-gnu`
section of the target since `linux-gnu` is needed in the testsuite.
This patch also moves the removal of minor and patchlevel numbers from OSX
triples to be handled when deducing the triple instead of when adding available
features.

The comma operators in the test iterators give better error messages when they
are deleted as opposed to not defined. Delete these functions when possible.

Summary:
An evil user might overload operator comma. Use a void cast to make sure any user overload is not selected.
Modify all the test iterators to define operator comma.
