Implement attribute progmem on reduced Tiny cores by adding
flash offset 0x4000 to respective symbols.
PR target/71948
* doc/extend.texi (AVR Variable Attributes) [progmem]: Add
documentation how it works on reduced Tiny cores.
(AVR Named Address Spaces): No support for reduced Tiny.
* config/avr/avr.c (AVR_SYMBOL_FLAG_TINY_PM): New macro.
(avr_address_tiny_pm_p): New static function.
(avr_print_operand_address) [AVR_TINY]: Add AVR_TINY_PM_OFFSET
if the address is in progmem.
(avr_assemble_integer): Same.
(avr_encode_section_info) [AVR_TINY]: Set AVR_SYMBOL_FLAG_TINY_PM
for symbol_ref in progmem.
* config/avr/avr.h (AVR_TINY_PM_OFFSET): New macro.
* config/avr/avr-c.c (avr_cpu_cpp_builtins): Use it instead of
magic 0x4000 when built-in def'ing __AVR_TINY_PM_BASE_ADDRESS__.
