caa97ca11f [libcxx] [test] D27024: Fix MSVC warning C4389 "signed/unsigned mismatch", part 11/12. 
Change "unsigned n = 0;" to "int n = 0;". It's being compared to int elements and ptrdiff_t distances.

test/std/containers/sequences/forwardlist/forwardlist.cons/move.pass.cpp
This one's a little special, but not really. "*i == n" is comparing MoveOnly to n.
MoveOnly is implicitly constructible from int, so int is the correct type to use here.

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.

c7011af19b Allow enabling/disabling testing with module using env LIBCXX_USE_MODULES=1 
The Clang modules implementation breaks enough that libc++ needs an easy way
to enable/disable using modules on the Zorg builders. Editing Zorg itself
requires a buildmaster restart which only happens weekly. This patch
allows LIBCXX_USE_MODULES to be used to enable/disable the feature,
allowing the buildslave to disable it as need be.

bca6de0e4e Adjust libc++ test infastructure to fully support modules 
This patch overhalls the libc++ test format/configuration in order to fully support modules. By "fully support" I mean get almost all of the tests passing. The main hurdle for doing this is handling tests that `#define _LIBCPP_FOO` macros to test a different configuration. This patch deals with these tests in the following ways:

1. For tests that define single `_LIBCPP_ABI_FOO` macros have been annotated with `// MODULES_DEFINES: _LIBCPP_ABI_FOO`. This allows the test suite to define the macro on the command line so it uses a different set of modules.
2. Tests for libc++'s debug mode (which define custom `_LIBCPP_ASSERT`) are automatically detected by the test suite and are compiled and run with modules disabled.

This patch also cleans up how the `CXXCompiler` helper class handles enabling/disabling language features.

NOTE: This patch uses `LIT` features which were only committed to LLVM today. If this patch breaks running the libc++ tests you probably need to update LLVM.

c6d8e8a9cc [libc++] Add _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS 
It's useful to be able to disable visibility annotations entirely; for
example, if we're building libc++ static to include in another library,
and we don't want any libc++ functions getting exported out of that
library. This is a generalization of _LIBCPP_DISABLE_DLL_IMPORT_EXPORT.

d59e3c7fed Handle tests for noexcept that expect a false value 
Under libcpp-no-exceptions, noexcept is trivially true. Some tests expect in
the usual setting to return false, so adjust them to expect true under
libcpp-no-exceptions.

0c2ffb6670 Choose better hash values for std::monostate and valueless variants. 
Previously these hashes were 0 and -1 respectively. These seem like common
sentinel values and should be avoided to prevent needless collisions.

This patch changes those values to different arbitrary numbers, which should
hopefully cause less collisions. Because I couldn't help myself I choose the
fundamental constants for gravity and the speed of light.
