If this test triggers anywhere for anyone, revert this commit immedeatly.
Ill revert this in a day or 2, its just so we know beforehand if the idea

initialized by ff_fft_init and using different code can result in slightly
different values, in addition it crashes when the tables are hardcoded.
On amd64 this slightly changes qdm2 output.

This hopefully is fast enough so that it is reasonable to use the same formula
directly instead of the table for CONFIG_SMALL.

--enable-hardcoded-tables was used.
Due to the size, the code for the tables is generated at compile time.
