      This RFE will allow AOT code generated on a newer CPU (e.g., one that has AVX3 instructions) to be executed on an older CPU (e.g., one that has only AVX2).

      For each architecture (x64, aarch64) we should decide a generic set of CPU features that would cover most modern CPUs.

      One idea is to add a new -XX: flag to specify that generic AOT code should be generated in the assembly phase.

      More details TBD.
