Chandler Carruth 20c5693e9e Teach the pass manager's execution dump to print the current time before 
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.

Rafael Espindola b1c1c5f377 Fix a FIXME about the format and add a test. 
While at it, use strftime on Unix too and use the thread safe versions
of localtime.

Alexey Samsonov f940f0c417 Fix initialization-order bug in llvm::Support::TimeValue. TimeValue::now() 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.
