lavc/dsd_tablegen: speed up table generation
Tables are bit identical.
Sample benchmark (Haswell, GNU/Linux+gcc):
old:
814485 decicycles in dsd_ctables_tableinit, 512 runs, 0 skips
new:
356808 decicycles in dsd_ctable_tableinit, 512 runs, 0 skips
Binary size should essentially be identical, and is in fact identical on
the configuration I tested on.
