Remove the x86 MOV{32,64}{rr,rm,mr}_TC instructions.
The reg-reg copies were no longer being generated since copyPhysReg copies
physical registers only.
The loads and stores are not necessary - The TC constraint is imposed by the
TAILJMP and TCRETURN instructions, there should be no need for constrained loads
and stores.
