PIN is very old and not compiler-friendly enough for today's toolchains. So I remove all PIN related code and reimplement them with the novel ISA RISC-V because it is more simple compared to x86's multiple instructions.
Now this version support reading trace exported from qemu_tracer and integrate the tracing mechanism with zsim's inner simulation.
