re PR java/5489 (-fverbose-asm crashes jc1 on ARM cross-compiler)

PR java/5489
* arm.md (return, sibcall_epilogue): Pass const_true_rtx as the
operand argument to output_return_instruction.
* arm.c (arm_print_operand, case 'd'): If the operand is
const_true_rtx then just return.
(arm_print_operand, case 'D'): If the operand is const_true_rtx
then abort.
