* arm-tdep.h (enum struct_return): New.
(struct gdbarch_tdep): Add struct_return member.
* arm-tdep.c (arm_return_value): Return
RETURN_VALUE_STRUCT_CONVENTION for aggregates when the ABI uses
pcc_struct_return.
(arm_gdbarch_init): Default to reg_struct_return.
* armobsd-tdep.c (armobsd_init_abi): Set pcc_struct_return.
