[X86] Teach X86FixupBWInsts to promote MOV8rr/MOV16rr to MOV32rr. This re-applies r268760, reverted in r268794. Fixes http://llvm.org/PR27670 The original imp-defs assertion was way overzealous: forward all implicit operands, except imp-defs of the new super-reg def (r268787 for GR64, but also possible for GR16->GR32), or imp-uses of the new super-reg use. While there, mark the source use as Undef, and add an imp-use of the old source reg: that should cover any case of dead super-regs. At the stage the pass runs, flags are unlikely to matter anyway; still, let's be as correct as possible. Also add MIR tests for the various interesting cases. Original commit message: Codesize is less (16) or equal (8), and we avoid partial dependencies.
