(cbranch_trace): Add member rtx* condition_rtx_in_insn, initialize it
accordingly in constructor.
(cbranch_trace::branch_condition_rtx_ref): New function.
(cbranch_trace::branch_condition_rtx): Use branch_condition_rtx_ref.
(sh_treg_combine::try_invert_branch_condition): Invert condition rtx
in insn using reversed_comparison_code and validate_change instead of
invert_jump_1.
(sh_treg_combine::execute): Look for conditional insns in basic blocks
in addition to conditional branches.
* config/sh/sh.md (*movsicc_div0s): Remove combine patterns.
