Afraid not.  And actually its more than just this commit causing CodeGen/IR in MC.

On X86, Utils/X86ShuffleDecode causes the MC layer there to pull in all of libCore.

Similarly, (I think this is X86 again), any use of libObject causes llvmCore to be linked because of IRObjectFile.  I think X86 uses some of libObject in its MC code for MachO relocations.
