This patch caused ICE for arm-none-eabi target:

Richard Earnshaw has already reported this in the PR, and here is my fix for that. I don't have any arm boxes, so will just test it on x86_64-linux and i686-linux (the PR44694 patch has been tested also on ppc/ppc64/s390/s390x btw), could you please test it on arm? Thanks.

	PR debug/44694
	* dwarf2out.c (reg_loc_descriptor): For eliminated arg_pointer_rtx
	or frame_pointer_rtx use DW_OP_fbreg offset DW_OP_stack_value.

Yes. This fixes the ICE I saw. Thanks!
