0.9.12.14:
        Get rid of some low-level hotspots in the compiler:

        * Use simple-arrays for assembler segment buffers.
        * Move the checking of policy variable name validity from run-time
          to compile-time where possible.
        * In POLICY, don't fetch the values of optimization qualities that
          aren't used in the body.
        * When creating debug-names, don't call FORMAT when encountering
          values of unhandled types. Instead mark them with a suitable
          s-exp.
