Emit debug_insn for CPU_LOG_TB_OP_OPT as well.
For all targets that currently call tcg_gen_debug_insn_start,add CPU_LOG_TB_OP_OPT to the condition that gates it.
This is useful for comparing optimization dumps, when thepre-optimization dump is merely noise....

Kill off cpu_state_reset()
In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset()was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all...
