AVR: Use avr_byte instead of simplify_gen_subreg (QImode, ...
There are many places where asm output functions have to look at
the constituent bytes and words of the operands. The function of
choice was simplify_gen_subreg (mode, ...) which can be replaced
by the more handy avr_byte (rtx, byte_num).
gcc/
* config/avr/avr.cc: Use functions like avr_byte,
avr_word, avr_[u]int8/16 if convenient.
(avr_uint16): New function.
