f182038521 literal suffixes for std::chrono 
git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@187078 91177308-0d34-0410-b5e6-96231b3b80d8

39213641f4 Debug mode for unordered_set. I believe this to be fairly complete for 
unordered_set, however it is not complete yet for unordered_multiset,
unordered_map or unordered_multimap.  There has been a lot of work done
for these other three containers, however that work was done just to
keep all of the tests passing.

You can try this out with -D_LIBCPP_DEBUG2.  You will have to link to a
libc++.dylib that has been compiled with src/debug.cpp.  So far, vector
(but not vector<bool>), list, and unordered_set are treated.  I hope to
get the other three unordered containers up fairly quickly now that
unordered_set is done.

The flag _LIBCPP_DEBUG2 will eventually be changed to _LIBCPP_DEBUG, but
not today.  This is my second effort at getting debug mode going for
libc++, and I'm not quite yet ready to throw all of the work under the
first attempt away.

The basic design is that all of the debug information is kept in a
central database, instead of in the containers.  This has been done as
an attempt to have debug mode and non-debug mode be ABI compatible with
each other.  There are some circumstances where if you construct a
container in an environment without debug mode and pass it into debug
mode, the checking will get confused and let you know with a readable
error message.  Passing containers the other way: from debug mode out to
a non-debugging mode container should be 100% safe (at least that is the
goal).

b66e1c3f96 Removed extension in [unordered_][multi]map which allowed one to emplace using just an argument for the key, as opposed to using piecewise_construct. However a bug report exposed that this created an unfortunate ambiguity. People who are currently using the extension will be notified the next time they compile, and will have to change to using piecewise_construct.

839ae58c2e Matthew Dempsky: In libc++'s <locale>, there's already dependence on an snprintf_l 
implementation and all of the char buffers readily have their
allocated size available, so we can easily use snprintf_l instead of
sprintf_l.

This avoids OpenBSD's linker warnings against using sprintf and
vsprintf.

312926eed4 Matthew Dempsky: POSIX defines that the _POSIX_C_SOURCE macros are to be set by user 
code to specify what version of POSIX the system should provide.  If
you want to check what version of POSIX is actually available, you're
supposed to test _POSIX_VERSION.

However, since sysconf() has been in POSIX since 1995, it's probably
safe to assume it's available on any system with a C++11 compiler,
especially if _SC_NPROCESSORS_ONLN is defined too.  So no point in a
complicated preprocessor rule if just we unconditionally include
<unistd.h> (on non-Windows systems).

Also, I've added a #warning for to help porters detect when a suitable
implementation isn't detected at compile-time.

Howard:  Matthew, can you patch CREDITS.TXT?  Thanks.
