* arm-tdep.h (ARM_MAX_REGISTER_RAW_SIZE): Define.

(ARM_MAX_REGISTER_VIRTUAL_SIZE): Define.
* arm-tdep.c (arm_store_return_value): Use them.
Use FP_REGISTER_RAW_SIZE when setting the FPA return value.
* remote-rdp.c (remote_rdp_fetch_register): Use
ARM_MAX_REGISTER_RAW_SIZE.
(remote_rdp_store_register): Likewise.
