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.

anchor methods to others. This eliminates the vtable/template method bloat
in .o files that defining a cl::opt used to impose (~4K per .o file for one
cp::opt<unsigned>).

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.

Adjust usage of the ExecuteAndWait function to use the last argument which
is the ErrMsg string. This is necessitated because this function no longer
throws exceptions on error.
llvm-svn: 29791
Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be
executed. Only one case (in bugpoint) actually examines the result code.

instead of throwing an exception. This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore
