avcodec/mathops: Set hidden visibility where advantageous It is advantageous for ff_crop_tab, as the base pointer used to access this table is not the first element of it. But the real base pointer is still at a constant offset from the code/the GOT and can therefore be accessed relative to the instruction pointer (if supported by the arch) or relative to the GOT; without this, one has to first load address of ff_crop_tab (potentially via the GOT) and then offset manually (which is what the earlier code did).
