MSVC compile error with trunk

Does not seem to be a straight error with LLVM itself, but rather the
tools, linking issues, here are the errors:

Yes, I know they are mostly duplicated linking errors, but this also
shows all the apps that fail as well, since not all fail.
This was with MSVC2k5 in debug build, happens in all build types though.

Please prepare a patch, thanks!

Confirmed, once IVUsers.cpp is added to the LLVMAnalysis library,
fixed some of those errors, but there are more still. Patch is
attached for the IVUsers.cpp add to the CMakeLists.txt file.

Do note, this linking error appears a few times, but they are all
identical to this one, looks like the last.

Yep, missing ShrinkWrapping.cpp in the lib\CodeGen\CMakeLists.txt
file. Have not tested (out of time, need to stop this), but I am
rather certain that it is just that problem now.
