* dwarf2out.c (mem_loc_descriptor) <case SUBREG>: Pass mem_mode
instead of mode as 3rd argument to recursive call.
(mem_loc_descriptor) <case REG>: If POINTERS_EXTEND_UNSIGNED, don't
emit DW_OP_GNU_regval_type if mode is Pmode and mem_mode is not
VOIDmode.
(mem_loc_descriptor) <case SYMBOL_REF>: If POINTERS_EXTEND_UNSIGNED,
don't give up if mode is Pmode and mem_mode is not VOIDmode.
(mem_loc_descriptor) <case CONST_INT>: If POINTERS_EXTEND_UNSIGNED,
use int_loc_descriptor if mode is Pmode and mem_mode is not VOIDmode.
