684bd46a57 2008-10-17-SpillerBug.ll is currently failing, but this doesn't reflect an actual regression of PR2898. This test should probably be removed. I've XFAILed it for now to keep buildbot quiet while this is considered.

92adc19be9 Adds extern "C" ints to the .cpp files that use RegisterTarget, as 
well as 2 files that use "Registrator"s. These are to be used by the
MSVC builds, as the Win32 linker does not include libs that are
otherwise unreferenced, even if global constructors in the lib have
side-effects.
