  Log:
  Initial x86-64 (aka amd64) support.
  
  Unregisterised it works perfectly.  Registerised, I think it's almost
  there, except that I seem to be running into the known codegen bug in
  GCC with register variables (bug #7871 in the gcc bugzilla), which
  means registerised support is basically hosed until the GCC folks
  can get their act together.
  
  We get 8 more registers on amd64, but only 2 more callee-saves
  registers.  The calling convention seems to pass args in registers by
  default, using the previously-callee-saves %rsi and %rdi as two of the
  new arg registers.
  
  I think GHCi should work, since we already have 64-bit ELF support
  thanks to Mat Chapman's work on the IA64 port.  I haven't tried GHCi,
  though.
  
  The native code generator should be a breeze, because it's so similar
  to plain x86.
