Log:
    Backport from 2013-01-07 trunk r194991, r194992.
    PR target/55897
    * doc/extend.texi (AVR Named Address Spaces): __memx goes into
    .progmemx.data now.
    * config/avr/avr.h (ADDR_SPACE_COUNT): New enum.
    (avr_addrspace_t): Add .section_name field.
    * config/avr/avr.c (progmem_section): Use ADDR_SPACE_COUNT as
    array size.
    (avr_addrspace): Same.  Initialize .section_name.  Remove last
    NULL entry.  Put __memx into .progmemx.data.
    (progmem_section_prefix): Remove.
    (avr_asm_init_sections): No need to initialize progmem_section.
    (avr_asm_named_section): Use avr_addrspace[].section_name to get
    section name prefix.
    (avr_asm_select_section): Ditto.  And use get_unnamed_section to
    retrieve the progmem section.
    * avr-c.c (avr_cpu_cpp_builtins): Use ADDR_SPACE_COUNT as loop
    boundary to run over avr_addrspace[].
    (avr_register_target_pragmas): Ditto.
