The idea was to push code generation as near as possible of code execution. Because at execution time, you know what are the specific features of the CPU, and what is used to most often by the user of the program.
In Free Software you have that already - it is called the source code. If you want host-specific optimizations use Gentoo Linux.
But that approach (incl. the possible LLVM JIT) has its own kind of disadvantages such as unreproducibility of compilation-specific problems elsewhere - no way to have meaningful build-ids, ABRT retrace server etc.
