Subject: [PATCH] perf: adjust compile flags for runtime performance (#314)

* Tell rustc to target the CPU that it's running on; this brings the trade-off that compiled binaries may not be appropriate for execution on arbitrary target systems.
* Set lto setting to fat
* Configure panicking on abort (no unwinding)
