      Give up on doing in-line instruction simplification during correlated value propagation.  Instruction simplification
      needs to be guaranteed never to be run on an unreachable block.  However, earlier block simplifications may have
      changed the CFG to make block that were reachable when we began our iteration unreachable by the time we try to
      simplify them. (Note that this also means that our depth-first iterators were potentially being invalidated).
      
      This should not have a large impact on code quality, since later runs of instcombine should pick up these simplifications.
      Fixes PR8506.

      Now that the profitable bits of EnableFullLoadPRE have been enabled by default, rip out the remainder.
      Anyone interested in more general PRE would be better served by implementing it separately, to get real
      anticipation calculation, etc.

      Massive rewrite of MMX: · dd224d23
      Dale Johannesen authored
      The x86_mmx type is used for MMX intrinsics, parameters and
      return values where these use MMX registers, and is also
      supported in load, store, and bitcast.
      
      Only the above operations generate MMX instructions, and optimizations
      do not operate on or produce MMX intrinsics. 
      
      MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
      smaller pieces.  Optimizations may occur on these forms and the
      result casted back to x86_mmx, provided the result feeds into a
      previous existing x86_mmx operation.
      
      The point of all this is prevent optimizations from introducing
      MMX operations, which is unsafe due to the EMMS problem.
