      The live range of a register defined by an early clobber starts at the use slot,
      not the def slot.
      
      Except when it is an early clobber tied to a use operand. Then it starts at the
      def slot like a standard def.

      When passing a parameter using the 'byval' mechanism, inline code needs to be used · 6c25ca4f

      to perform the copy, which may be of lots of memory [*].  It would be good if the
      fall-back code generated something reasonable, i.e. did the copy in a loop, rather
      than vast numbers of loads and stores.  Add a note about this.  Currently target
      specific code seems to always kick in so this is more of a theoretical issue rather
      than a practical one now that X86 has been fixed.
      [*] It's amazing how often people pass mega-byte long arrays by copy...
