(aapcs_layout_arg): Emit -Wpsabi note if arm_needs_doubleword_align returns negative, increment ncrn if it returned non-zero. (arm_needs_doubleword_align): Return int instead of bool, ignore DECL_ALIGN of non-FIELD_DECL TYPE_FIELDS chain members, but if there is any such non-FIELD_DECL > PARM_BOUNDARY aligned decl, return -1 instead of false. (arm_function_arg): Emit -Wpsabi note if arm_needs_doubleword_align returns negative, increment nregs if it returned non-zero. (arm_setup_incoming_varargs): Likewise. (arm_function_arg_boundary): Emit -Wpsabi note if arm_needs_doubleword_align returns negative, return DOUBLEWORD_ALIGNMENT if it returned non-zero. * g++.dg/abi/pr77728-1.C: New test.
