* config/arm/arm.c (use_return_insn): Don't reject interrupt
functions.
(arm_compute_save_reg_mask): Save LR for interrupt functions too.
(output_return_instruction): Allow interrupt functions to return with
ldmfd sp!, {... pc}^. Use LDR to restore any single register.
(arm_expand_prologue): Subtract 4 before stacking LR in an
interrupt function.
