[AVR] Add 'avr3' and 'avr51' architectures.

Hello.

The 'avr3' and 'avr51' architectures contain devices with 16-128KB FLASH, but 128KB devices is difference from < 128KBdevices, they have ELPM instruction and RAMPZ register. This patch move 128KB devices in new architectures: ATmega103 in 'avr31' and ATmega128*, AT90CAN128, AT90USB128* in 'avr51'. And define "__AVR_HAVE_RAMPZ__", "__AVR_HAVE_ELPM__" and "__AVR_HAVE_ELPMX__"   macros  for these devices.

    * config/avr/avr.c (avr_current_arch): New variable.
    (avr_arch_types): Add 'avr31' and 'avr51' entries.
    (avr_arch): Add 'ARCH_AVR31' and 'ARCH_AVR51'.
    (avr_mcu_types): Add 'avr31' and 'avr51' architectures.
    (avr_override_options): Init 'avr_current_arch'. 
    (base_arch_s): Move from here...
    * config/avr/avr.h (base_arch_s): ... here. Add new members 
     'have_elpm', 'have_elpmx', 'have_eijmp_eicall', 'reserved'. Rename 
    'mega' to 'have_jmp_call'.
    (TARGET_CPU_CPP_BUILTINS): Define "__AVR_HAVE_JMP_CALL__", 
    "__AVR_HAVE_RAMPZ__",  "__AVR_HAVE_ELPM__" and  "__AVR_HAVE_ELPMX__"
    macros.
    (LINK_SPEC, CRT_BINUTILS_SPECS, ASM_SPEC): Add 'avr31' and 'avr51' 
    architectures.
    * config/avr/t-avr (MULTILIB_OPTIONS, MULTILIB_DIRNAMES, 
    MULTILIB_MATCHES): (Ditto.).
