re PR debug/69244 (ICE in plus_constant, at explow.c:87 on i686-linux-gnu)
PR debug/69244
* lra-eliminations.c (move_plus_up): Don't change anything if either
the outer or inner subreg mode is not MODE_INT.
* dwarf2out.c (mem_loc_descriptor): For SUBREG, if outer mode is
integral <= DWARF2_ADDR_SIZE, convert to untyped afterwards.
* gcc.dg/guality/pr69244.c: New test.
