Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Fix LICM/2003-12-11-SinkingToPHI.ll, and quite possibly all of the other known problems in the universe.

Make LICM itself a bit more efficient, and make the generated code more efficient too: don't insert a store in every exit block, because a particular block may be exited to more than once by a loop

llvm-svn: 10369

better job, but this is the majority of the work.  This implements
LICM/sink*.ll

llvm-svn: 10358

should make subsequent changes simpler.  This also allows us to hoist vaarg
and vanext instructions

Code cleanups
Make LICM::SafeToHoist marginally more efficient
