Hi,

I've committed this patch which is a couple fo tweaks to the dynamic 
configuration and profiling interfaces. basic_cpu::cg_profile and 
basic_cpu::cg_profile_jump are now virtual to allow for hooks by 
inheriting classes. basic_cpu::dynamic_config has been added in order to 
force --insn-count=1 when --trace-counter is on. This is needed in order 
that total_insn_count is updated after each insn.
