For PR780:
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
   with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

For PR780:
This change was suggested by Chris so that we can select an alternate
(or even no-op) implementation of the link assurance. I'm committing this
for your review, Chris. If the names and definitions are okay, I'll adjust
all the .h and .cpp files in a later patch.

For PR780:
Break the "IncludeFile" mechanism into its own header file and adjust other

Fix a bug in the following scenario.
1. llvm is built with objroot = OBJ and installed.
2. OBJ is deleted or install tree is shipped.
3. llvm-config is run.

In this scenario, llvm-config shouldn't emit an error message at #3, it
should just know it's not running in the objdir :)

Add a new --libfiles option, for getting fully-qualified pathnames to libraries.

Make the "pruning cloner" smarter.  As it propagates constants through the
code (while cloning) it often gets the branch/switch instructions.  Since it
knows that edges of the CFG are dead, it need not clone (or even look) at
the obviously dead blocks.  This should speed up the inliner substantially on
code where there are lots of inlinable calls to functions with constant
arguments.  On C++ code in particular, this kicks in.

Provide support for detecting if the Win32 imaghlp and psapi libraries
are available. These libraries are used in lib/System and should be
included on the link line or if not available generate an error when
building lib/System.

Fix a typo

Make a shorthand target for running the llvm2cpp test suite. This test
suite is disabled by default because of the length of time it takes to
run. To enable it certain command line fu must be used. This patch just
encodes the command line fu as the magical "check-llvm2cpp" target.

Restore default arguments for llvm2cpp back to health by declaring an
emitted variable to actually have a type (picky, picky, picky!)

Change from using a stub function to a stub variable for passing to the
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

More cleanups.  Also, add a special case for updating PHI nodes, and
reimplement getValueDominatingFunction to walk the DominanceTree rather than
just searching blindly.

For PR786:
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

Build llvm-config into the ToolDir not in the local directory. This makes
it more likely to be in a developer's path and consistent with all the
other tools.
