  setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
  that move kill / dead info to MachineInstr's.

Fix an infinite loop in the Linker and a few other assorted link problems.

Patch contributed by Scott Michel. Thanks, Scott!

link to previous frame.  This is a short term workaround until alloca scheme is
reworked.
