Comment:

 I fixed the out-of-range addqs recently:

   * x86_64: fix case of out-of-range operands to leaq

     M ./ghc/compiler/nativeGen/MachCodeGen.hs -3 +8

 The "movl %esi, %esi" is not a NOP in x86_64, it is actually a zero-
 extension from 32 to 64 bits in the esi/rsi register.  x86_64 assembly is
 pretty strange, sometimes.
