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.

Properly handle reloading and spilling around partial redefines in

LocalRewriter.
This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.
