    swscale/ops_optimizer: don't commute clear with itself

    swscale/ops_optimizer: apply optimizations in a more predictable order
Instead of blindly interleaving re-ordering and minimizing optimizations,
separate this loop into several passes - the first pass will minimize the
operation list in-place as much as possible, and the second pass will apply any
desired re-orderings. (We also want to try pushing clear back before any other
re-orderings, as this can trigger more phase 1 optimizations)

This restructuring leads to significantly more predictable and stable behavior,
especially when introducing more operation types going forwards. Does not
actually affect the current results, but matters with some upcoming changes
I have planned.

    Comments

    swscale/ops_optimizer: simplify loop slightly (cosmetic)
We always `goto retry` whenever an optimization case is hit, so we don't
need to defer the increment of `n`.

    swscale/format: only generate SHIFT ops when needed
Otherwise, we may spuriously generate illegal combinations like
SWS_OP_LSHIFT on SWS_PIXEL_F32.

    Comments

    swscale/ops: correctly truncate on ff_sws_apply_op_q(SWS_OP_RSHIFT)
Instead of using a "precise" division, simulate the actual truncation.

Note that the division by `den` is unneeded in principle because the
denominator *should* always be 1 for an integer, but this way we don't
explode if the user should happen to pass `4/2` or something.

Fixes a lot of unnecessary clamps w.r.t. xv36, e.g.:

 xv36be -> yuv444p12be:
   [u16 XXXX -> ++++] SWS_OP_READ         : 4 elem(s) packed >> 0
   [u16 ...X -> ++++] SWS_OP_SWAP_BYTES
   [u16 ...X -> ++++] SWS_OP_SWIZZLE      : 1023
   [u16 ...X -> ++++] SWS_OP_RSHIFT       : >> 4
-  [u16 ...X -> ++++] SWS_OP_CONVERT      : u16 -> f32
-  [f32 ...X -> ++++] SWS_OP_MIN          : x <= {4095 4095 4095 _}
-  [f32 ...X -> ++++] SWS_OP_CONVERT      : f32 -> u16
   [u16 ...X -> ++++] SWS_OP_SWAP_BYTES
   [u16 ...X -> ++++] SWS_OP_WRITE        : 3 elem(s) planar >> 0
     (X = unused, + = exact, 0 = zero)

    swscale/ops: update comment on SWS_COMP_EXACT
That the integer is "in-range" is implied by the min/max range tracking,
not the flag itself.
