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.

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.

Break the "IncludeFile" mechanism into its own header file and adjust other
files accordingly. Use this facility for the IntrinsicInst problem which
was the subject of PR800.
More to follow on this.

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 :)

function that is being lowered is forced to use FP. Currently this is only
true for main() / Cygwin.

This can be used for tools that want makefile rules to depend on the libraries
(e.g. so the tool is relinked when a library changes).

through to gcc when its being used as a linker. This allows -L and -l
(and any other) options to be added so that non-complete bytecode files
can be processed with bugpoint. The -Xlinker option can be added as many
times as needed.

built with CommandLine.h will want the --version option to report that the
tool belongs to LLVM. To override simply pass a void func() to the
cl::SetVersionPrinter() function and that void func() will be called when
it is time to print the version information.
