* dwarf2out.c (int_shift_loc_descriptor): New function.
(int_loc_descriptor): If shorter, emit i as
(i >> shift), shift, DW_OP_shl for suitable shift value.
Similarly, try to optimize large negative values using
DW_OP_neg of a positive value if shorter.
(size_of_int_shift_loc_descriptor): New function.
(size_of_int_loc_descriptor): Adjust to match int_loc_descriptor
changes.
(mem_loc_descriptor) <case CONST_INT>: Emit zero-extended constants
that fit into DWARF2_ADDR_SIZE bytes as int_loc_descriptor +
DW_OP_GNU_convert instead of DW_OP_GNU_const_type if the former
is shorter.
(resolve_addr_in_expr): Optimize DW_OP_plus_uconst with a large
addend as added DW_OP_plus if it is shorter.
* gcc.dg/guality/csttest.c: New test.
