     * Generic 64bit-to-32bit unary operation.  Provide an "instr" line
     * that specifies an instruction that performs "result = op a0/a1", where
     * "result" is a 32-bit quantity in a0.
     *
     * For: long-to-float, double-to-int, double-to-float
     * If hard floating point support is available, use fa0 as the parameter,
     * except for long-to-float opcode.
     * (This would work for long-to-int, but that instruction is actually
     * an exact match for OP_MOVE.)
