perf annotate-data: Handle call instructions
When updating instruction states, the call instruction should play a
role since it changes the register states. For simplicity, mark some
registers as caller-saved registers (should be arch-dependent), and
invalidate them all after a function call.
If the function returns something, the designated register (ret_reg)
will have the type info.
