98605940df [libcxx] [test] D27021: Fix MSVC warning C4389 "signed/unsigned mismatch", part 8/12. 
Add static_cast<std::size_t> when comparing distance() to size().

These replacements were performed programmatically with regex_replace():

const vector<pair<regex, string>> reg_fmt = {
    { regex(R"(assert\((\w+)\.size\(\) == std::distance\((\w+, \w+)\)\))"),
        "assert($1.size() == static_cast<std::size_t>(std::distance($2)))" },
    { regex(R"(assert\(distance\((\w+\.begin\(\), \w+\.end\(\))\) == (\w+)\.size\(\)\))"),
        "assert(static_cast<std::size_t>(distance($1)) == $2.size())" },
    { regex(R"(assert\(std::distance\((\w+\.\w*begin\(\), \w+\.\w*end\(\))\) == (\w+)\.size\(\)\))"),
        "assert(static_cast<std::size_t>(std::distance($1)) == $2.size())" },
};

Also, include <cstddef> when it wasn't already being included.

ef3060ef96 [libcxx] Fix max_size() across all containers 
Summary: The `max_size()` method of containers should respect both the allocator's reported `max_size` and the range of the `difference_type`. This patch makes all containers choose the smallest of those two values.

e619862dbf [libcxx] [test] Replace _LIBCPP_STD_VER with TEST_STD_VER. 
This replaces every occurrence of _LIBCPP_STD_VER in the tests with
TEST_STD_VER. Additionally, for every affected
file, #include "test_macros.h" is being added explicitly if it wasn't
already there.

d2864678e0 Fix LWG issue 2469 - Use piecewise construction in map::operator[]. 
map's allocator may only be used to construct objects of 'value_type',
or in this case 'pair<const Key, Value>'. In order to respect this requirement
in operator[], which requires default constructing the 'mapped_type', we have
to use pair's piecewise constructor with '(tuple<Kep>, tuple<>)'.

Unfortunately we still need to provide a fallback implementation for C++03
since we don't have <tuple>. Even worse this fallback is the last remaining
user of '__hash_map_node_destructor' and '__construct_node_with_key'.

This patch also switches try_emplace over to __tree.__emplace_unique_key_args.

cc2e93cff0 Make it possible to build a no-exceptions variant of libcxx. 
Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.

This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.
