ced7928069 libcxx: Fix path.compare.pass expected result 
The expected 'filesystem::path::compare' result states that for different
path only result sign contains the information about passed arguments
(not its integer value).  This is due it uses the output of other compare
functions (basic_string_view and char_traits) without further handling and
char_traits uses memcmp for final buffer comparison.

However for GLIBC on AArch64 the code:

  int ret = memcmp ("b/a/c", "a/b/c", 1);

Results in '64' where for x86_64 it results in '1'.

This patch fixes the expected 'filesystem::path::compare' by normalizing
all the results before assert comparison.

f5b8d8249e test: relax the FS test a slight bit to be more reliable 
Some filesystems track atime always.  This relaxes the test to accept either a
filesystem which does not accurately track atime or does track the atime
accurately.  This allows the test to pass on filesystems mounted with
`strictatime` on Linux or on macOS.

324506b9f3 [libcxx] Add std::any 
Summary:
This patch adds std::any by moving/adapting <experimental/any>.

This patch also implements the std::any parts of p0032r3 (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0032r3.pdf)
and LWG 2509 (http://cplusplus.github.io/LWG/lwg-defects.html#2509).

I plan to push it in a day or two if there are no comments.

45b7b44867 Implement LWG 2148: Make non-enum default hash specialization well-formed 
Summary:
This patch removes the static_assert for non-enum types in the primary hash template. Instead non-enum types create a hash<T> specialization that is not constructible nor callable.

2fdf202493 [libcxx] Add "flag" default arg: basic_regex ptr_size_flag ctor 
Summary:
The synopsis in C++11 subclause 28.8 [re.regex] has:
```
basic_regex(const charT* p, size_t len,
            flag_type f = regex_constants::ECMAScript);
```

The default argument is added to libc++ by this change.

In the synopsis in C++11 subclause 28.8 [re.regex], `basic_regex` is

189f88ca35 Revert r276548 - Make pair/tuples assignment operators SFINAE properly. 
This is a breaking change. The SFINAE required is instantiated the second
the class is instantiated, and this can cause hard SFINAE errors
when applied to references to incomplete types. Ex.

struct IncompleteType;
extern IncompleteType it;
std::tuple<IncompleteType&> t(it); // SFINAE will blow up.

4e91ea50a0 Don't SFINAE pair's copy assignment operator in C++03 mode. 
In C++03 mode evaluating the SFINAE can cause a hard error due to
access control violations. This is a problem because the SFINAE
is evaluated as soon as the class is instantiated, and not later.
