    swscale/graph: re-check pixel format support in add_legacy_sws_pass()
When the user passes multiple backends (e.g. SWS_BACKEND_ALL), the
static check in sws_setup_frame() might have succeeded for the ops
backend but not the legacy backend, so we need to properly restrict
the legacy backend implementation function as well. Otherwise, this
may trigger internal errors / AVERROR(EINVAL) inside sws_init_context().

    swscale/tests/swscale: refactor format testing logic
Uses the internal ff_sws_test_pixfmt_backend() to test for format support
on the concrete backend that's in-use for the auxiliary/main conversions,
respectively, while taking into account the -backends and -api options.

    swscale/swscale_unscaled: disable unscaled copy from yaf32be to grayf32be
yaf32be input wasn't being properly filtered out of the simple copy
condition when converting to grayf32be, which caused half the luma
plane to be interleaved with half the alpha plane, instead of just
copying the luma plane.

This fixes:
$ ./libswscale/tests/swscale -scaler none -src yaf32be -dst grayf32be
yaf32be 96x96 -> grayf32be 96x96, flags=0x0 dither=1 scaler=0/0, SSIM={Y=0.866842 U=1.000000 V=1.000000 A=1.000000} loss=1.065262e-01
yaf32be 96x96 -> grayf32be 96x96, flags=0x0 dither=1 scaler=0/0
  loss 1.065262e-01 is WORSE by 1.065202e-01, expected loss 6.020069e-06

    tests/fate/sws-unscaled: constrain to -backends unstable
This is more explicit than -flags unstable, because it also excludes
any pixel formats that are only handled by the legacy code.

    swscale/graph: prefer ops backend for floating point formats
These have horrible support in legacy swscale; in particular, they break the
pixel range (limited vs full) when converting to yuva444p, resulting in SSIM
errors like:

uyva 96x96 -> grayf32le 96x96, SSIM={Y=0.997654 U=1.000000 V=1.000000 A=1.000000} loss=1.876414e-03
  loss 1.876414e-03 is worse by 1.864254e-03, expected loss 1.215935e-05

(The ops-based backend gets a 100% bit-exact roundtrip here)

    tests/fate: add fate-sws-unstable test
The fate test for unscaled conversions (fate-sws-unscaled) does not
test the filtering (scaling) paths.

This commit adds a test for all the scaling paths for the new swscale
code, but only runs 2% of the tests (otherwise this test alone would
take about two and a half minutes on a modern x86_64 machine).

    swscale/aarch64/ops_asmgen: fold impl pointer increment into loading of continuation address
This commit reduces every kernel by one instruction, for example:
 function ff_sws_clear_8_u16_0001_neon, export=1, jumpable=1
-        ldr             x0, [x1]                        // SwsFuncPtr cont = impl->cont;
         ldr             q16, [x1, #16]                  // v128 clear_vec = impl->priv.v128;
+        ldr             x0, [x1], #32                   // SwsFuncPtr cont = (impl++)->cont;
         dup             v0.8h, v16.h[0]                 // vl[0] = broadcast(clear_vec[0])
-        add             x1, x1, #32                     // impl += 1;
         br              x0                              // jump to cont
 endfunc

A55: Overall speedup=1.066x faster, min=0.881x max=1.288x
A76: Overall speedup=1.012x faster, min=0.570x max=1.546x

The large min/max differences are due to pathological branch miss cases
that happen either before of after this commit.
