Dan Gohman 16e8eda4b8 Fix ScheduleDAGRRList::CopyAndMoveSuccessors' handling of nodes
with multiple chain operands. This can occur when the scheduler
has added chain operands to a node that already has a chain
operand, in order to handle physical register dependencies.

This fixes an llvm-gcc bootstrap failure on x86-64 introduced
in r66058.
