Revert part of 70929 that has to do with determining whether a SIB byte is needed. It causes a lot of x86_64 JIT failures.

Allow multiclass def names to contain "#NAME"" where TableGen replaces
#NAME# with the name of the defm instantiating the multiclass.  This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA.  For example:

multiclass SSE_AVX_Inst<...> {
   def SS : Instr<...>;
   def SD : Instr<...>;
   def PS : Instr<...>;
   def PD : Instr<...>;

   def V#NAME#SS : Instr<...>;
   def V#NAME#SD : Instr<...>;
   def V#NAME#PS : Instr<...>;
   def V#NAME#PD : Instr<...>;
}

defm ADD : SSE_AVX_Inst<...>;

- Synchronize instruction length computation code in X86InstrInfo with code in X86CodeEmitter.cpp
Patch by Zoltan Varga.

llvm-svn: 70929

CallbackVH, with fixes. allUsesReplacedWith need to
walk the def-use chains and invalidate all users of a
value that is replaced. SCEVs of users need to be
recalcualted even if the new value is equivalent. Also,
make forgetLoopPHIs walk def-use chains, since any
SCEV that depends on a PHI should be recalculated when
more information about that PHI becomes available.

  ThreadEdge directly.  This shares the code, but is just a refactoring.
* Make JumpThreading compute the set of loop headers and avoid threading
  across them.  This prevents jump threading from forming irreducible 
  loops (goodness) but also prevents it from threading in other cases that
  are beneficial (see the comment above FindFunctionBackedges).

The stack slots which share the same stack slot after coloring can, but do not have to, use the same register. In fact, they each may have different register class requirements.
