Most of the avr built-in functions can be attributed "const".
Ok for trunk?

--
AVR: Add "const" attribute to avr built-in functions if possible.
gcc/
* config/avr/avr-c.cc (DEF_BUILTIN): Add ATTRS argument to macro
definition.
* config/avr/avr.cc: Same.
(avr_init_builtins) <attr_const>: New variable that can be used
as ATTRS argument in DEF_BUILTIN.
* config/avr/builtins.def (DEF_BUILTIN): Add ATTRS parameter
to all definitions.
