AVR: Rework patterns that add / subtract an (inverted) MSB.
gcc/
* config/avr/avr-protos.h (avr_out_add_msb): New proto.
* config/avr/avr.cc (avr_out_add_msb): New function.
(avr_adjust_insn_length) [ADJUST_LEN_ADD_GE0,
ADJUST_LEN_ADD_LT0]: Handle cases.
* config/avr/avr.md (adjust_len) <add_lt0, add_ge0>: New attr values.
(QISI2): New mode iterator.
(C_MSB): New mode_attr.
(*add<mode>3...msb_split, *add<mode>3.ge0, *add<mode>3.lt0)
(*sub<mode>3...msb_split, *sub<mode>3.ge0, *sub<mode>3.lt0): New
patterns replacing old ones, but with iterators and
using avr_out_add_msb() for asm out.
