Summary: A53 scheduler causes an assertion failure on all CRC instructions: include/llvm/CodeGen/MachineInstr.h:280: const llvm::MachineOperand &llvm::MachineInstr::getOperand(unsigned int) const: Assertion `i < getNumOperands() && "getOperand() out of range!"' failed. The case statements corresponding to CRC instructions are incorrect and should be removed. Also adding a testcase while on this.
