  avcodec/cbrt_tablegen: Reduce size of LUT only used once
  
  ff_cbrt_tableinit{,_fixed}() uses a LUT of doubles of the same size
  as the actual LUT to be initialized (8192 elems). Said LUT is only
  used to initialize another LUT, but because it is static, the dirty
  memory (64KiB) is not released. It is also too large to be put on
  the stack.
  
  This commit mitigates this: We only use a LUT for the powers of
  odd values, thereby halving its size. The generated LUT stays unchanged.

  avcodec/cbrt_tablegen: Remove always-false branch
  
  Each ff_cbrt_tableinit*() is called at most once, making this
  check always-false.

  checkasm: sw_ops: Avoid division by zero
  
  If we're invoked with range == UINT_MAX, we end up doing
  "rnd() % (UINT_MAX + 1)", which is equal to "rnd() % 0". On
  arm (on all platforms) and on MSVC i386, this ends up crashing
  at runtime.
  
  This fixes the crash.
