This dependency inversion wasn't entirely successful (and has broken the
modules build): MC still depends on Object. In particular:

$ rgrep '#include "llvm/Object' MC
MC/MCObjectSymbolizer.h:#include "llvm/Object/ObjectFile.h"

Now that we have a lib/MC/MCAnalysis, the dependency was there just because
