This fails to compile with every single toolchain I tested it with. It 
fails to compile on Apple Clang 12, LLVM.org Clang (nightly), GCC 7, GCC 
9, MSVC.

It fails with various incarnations of this issue:

src/libavcodec/aarch64/hevcdsp_init_aarch64.c:140:9: error: use of 
undeclared identifier 'ff_hevc_put_hevc_pel_pixels4_8_neon'
         NEON8_FNASSIGN(c->put_hevc_qpel, 0, 0, pel_pixels);

Not spending time on reviewing it in this form.
