Extend __pgmx semantics to linearize memory.
* config/avr/avr.md (mov<mode>): Use avr_xload_libgcc_p to
determine if code comes inline or from libgcc.
(MOVMEM_r_d:HI): Add "w" to constraint for better preference.
(movmem_qi, movmem_qi): Set constraint #2 to "n".
(movmem_qi_elpm, movmem_hi_elpm): Remove insns.
(movmemx_qi, movmemx_hi): New insns.
(xload_<mode>_libgcc): Rewrite to new insn condition.
(xload_<mode>): Remove insns.
* config/avr/avr.c (avr_out_xload): Rewrite: Only need to handle
cases that don't satisfy avr_xload_libgcc_p().
(avr_addr_space_convert): Allow converting in any direction.
(avr_addr_space_subset_p): Return always true.
(avr_xload_libgcc_p): Rewrite to fit new __pgmx semantics.
(avr_emit_movmemhi): Ditto.
(avr_out_lpm): No need to handle ADDR_SPACE_PGMX any more.
(avr_out_movmem): Ditto.
(AVR_SYMBOL_FLAG_PROGMEM): New macro.
(AVR_SYMBOL_SET_ADDR_SPACE): New macro.
(AVR_SYMBOL_GET_ADDR_SPACE): New macro.
(avr_encode_section_info): Encode 'progmem' in symbol flags.
(output_reload_in_const): Don't zero-extend any 24-bit symbols.
