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.

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.

IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

Don't warn about -pedantic errors. Add a note to the PR instead.

llvm-svn: 28616

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.
