    double-float-bits for x86/sse2. This gives x86 the same
    micro-optimizations that were available for sparc and ppc.
     o code/kernel.lisp:
       o Enable fast double-float-bits using the vop instead of calling
     o compiler/float-tran.lisp:
       o Make fast-unary-ftruncate known to compiler and enable optimizer
         for it. 
       o Make double-float-bits known to compiler
     o compiler/x86/float-sse2.lisp:
       o Implement fast-unary-ftruncate for singles and doubles.
       o Implement double-float-bits.
