-/* ??? These are old notes, kept around for now.
-   Collecting profile data and tracing slow us down so we don't do them in
-   "fast mode".
-   There are 6 possibilities on 2 axes:
-   - no-scaching, insn-scaching, basic-block-scaching
-   - run with full features or run fast
-   Supporting all six possibilities in one executable is a bit much but
-   supporting full/fast seems reasonable.
-   If the scache is configured in it is always used.
-   If pbb-scaching is configured in it is always used.
-   ??? Sometimes supporting more than one set of semantic functions will make
-   the simulator too large - this should be configurable.  Blah blah blah.
-   ??? Supporting full/fast can be more modular, blah blah blah.
-   When the framework is more modular, this can be.
