      Codegen things like: · 2771e2c9

       <int -1, int -1, int -1, int -1>
      and
       <int 65537, int 65537, int 65537, int 65537>
      
      Using things like:
        vspltisb v0, -1
      and:
        vspltish v0, 1
      
      instead of using constant pool loads.
      
      This implements CodeGen/PowerPC/vec_splat.ll:splat_imm_i{32|16}.

      When possible, custom lower 32-bit SINT_TO_FP to this: · 4a66d694

      This speeds up Misc/pi from 2.44s->2.09s with LLC and from 3.01->2.18s
      with llcbeta (16.7% and 38.1% respectively).

      Add an initial hack at legalizing GlobalAddress into the appropriate nodes · 595088aa
      Chris Lattner authored
      on Darwin to remove smarts from the isel.  This is currently disabled by
      default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
      tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
      needed to be added to the .td file.  However, we can currently emit stuff like
      this:  :)
      
              li r2, lo16(L_x$non_lazy_ptr)
              lis r3, ha16(L_x$non_lazy_ptr)
              lwzx r2, r3, r2
      
      The obvious improvements will follow.
