This is a resubmission of r284590. The mingw build should be fixed now. The
problem was we were matching time_t with _localtime_64s, which was incorrect on
_USE_32BIT_TIME_T systems. Instead I use localtime_s, which should always
evaluate to the correct function.

This reverts commit r284590 as it fails on the mingw buildbot. I think I know the
fix, but I cannot test it right now. Will reapply when I verify it works ok.
This reverts r284590.

Summary:
std::chrono mostly covers the functionality of llvm::sys::TimeValue and
lldb_private::TimeValue. This header adds a bit of utility functions and
typedefs, which make the usage of the library and porting code from TimeValues
easier.
Rationale:
- TimePoint typedef - precision of system_clock is implementation defined -
using a well-defined precision helps maintain consistency between platforms,
makes it interact better with existing TimeValue classes, and avoids cases
there a time point is implicitly convertible to a specific precision on some
platforms but not on others.
- system_clock::to_time_t only accepts time_points with the default system
precision (even though time_t has only second precision on all platforms we
support). To avoid the need for explicit casts, I have added a toTimeT()
wrapper function. toTimePoint(time_t) was not strictly necessary, but I have
added it for symmetry.

Apparently, the style needs to be agreed upon first.

each line. This is particularly nice for tracking which run of
a particular pass over a particular function was slow.
This also required making the TimeValue string much more useful. First,
there is a standard format for writing out a date and time. Let's use
that rather than strings that would have to be parsed. Second, actually
output the nanosecond resolution that timevalue claims to have.
This is proving useful working on PR19499, so I figured it would be
generally useful to commit.

While at it, use strftime on Unix too and use the thread safe versions
of localtime.

is explicitly called during module initialization of lib/Support/Process.cpp. It reads the field of global object PosixZeroTime, which is not guaranteed to be initialized at this point. Found by AddressSanitizer with -fsanitize=init-order option.
