88626bf496 First part of P0600 - '[[nodiscard] in the standard library'. Mark the 'empty()' methods of all the containers as nodiscard. If you're calling empty() w/o looking at the result, you probably meanto to call 'clear()'. c++2a only

3bea61851a [libcxx] [test] D27023: Fix MSVC warning C4389 "signed/unsigned mismatch", part 10/12. 
Add static_cast<int>. In these cases, the values are guaranteed to be small-ish,
and they're being compared to int elements.

test/std/containers/sequences/deque/deque.capacity/access.pass.cpp
Use int instead of unsigned to iterate from 0 to 10.

21208822a8 [libcxx] [test] D27022: Fix MSVC warning C4389 "signed/unsigned mismatch", part 9/12. 
Add static_cast<std::size_t> to more comparisons. (Performed manually, unlike part 8/12.)

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

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.

d24c465bea Replace __cplusplus comparisons and dialect __has_feature checks with TEST_STD_VER. 
This is a huge cleanup that helps make the libc++ test suite more portable.
Patch from STL@microsoft.com. Thanks STL!
