/* Time converter generator gadget. Selects from one of three

* precision conversion. Clever use of extra arguments causes all the
* selection logic to be optimized out, and the generated code even
* reduces to 32 bit only if a ratio conversion is available and the
* result is 32 bits.
*
* This isn't intended to be used directly, instead being wrapped
* appropriately in a user-facing API. The boolean arguments are:
*
* const_hz - The hz arguments are known to be compile-time
* constants (because otherwise the modulus test would
* have to be done at runtime)
* result32 - The result will be truncated to 32 bits on use
* round_up - Return the ceiling of the resulting fraction
* round_off - Return the nearest value to the resulting fraction
* (pass both round_up/off as false to get "round_down")
