  Log Message:
  -----------
  [GlobalISel] Also set dead flags of implicit defs added by BuildMI

BuildMI automatically adds the implicit operands of the
instruction. This meant we couldn''t set the dead flag on
dead implicit defs in that case.

Fix it by introducing an opcode to mark a given implicit
def as dead.

Fixes #64565
