stream. It centralizes the use of std::cerr so that static c'tor/d'tors
aren't scattered around all over the place. The way to use it is like this:

       DOUT << "This is a status line: " << Var << "\n";

If "-debug" is specified, it will print. Otherwise, it'll not print. If
NDEBUG is defined, the DOUT does nothing.

This library no longer throws nor handles exceptions, so turn off the
REQUIRES_EH flag.

Final remove of exception handling from this file. lib/System can no longer
throw exceptions so there's no need for try/catch blocks here.

portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages.  Instead of:
  /path/to/llvm/bin/directory/toolname: error message
we will now get:
  toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

Adjust users of MappedFile to its new non-throwing interface.  Note that in
most cases the lazy step of just throwing after a call to MappedFile was
installed. This was done in the name of incremental changes. Getting rid of
the new throw statements will take adjustment of interfaces and propagation
of errors to higher levels.  Those changes will come in subsequent patches.
