Add run-time CPU detection and support for ARM architecture
Run-time CPU detection (RTCD) is enabled by default if target platform support
it.
It can be disable at compile time with --disable-rtcd option.
Add RTCD support for ARM architecture.
Thanks to Timothy B. Terriberry for help and code review
