avr-protos.h (avr_out_sbxx_branch): Declare.
* config/avr/avr-protos.h (avr_out_sbxx_branch): Declare.
* config/avr/avr.c (jump_over_one_insn_p): Take length of the
branch insn into account, do not assume 1.
(avr_out_sbxx_branch): New function. Optimize cases of skipping
over single word insn. Handle upper half of I/O space too.
* config/avr/avr.md (*sbrx_branch): Use it.
(*sbrx_and_branchhi, *sbrx_and_branchsi): Likewise.
(*sbix_branch, *sbix_branch_bit7): Likewise.
(*sbix_branch_tmp, *sbix_branch_tmp_bit7): New.
Use RTL peepholes to optimize register operand sign tests.
