[FFmpeg-devel] [PATCH v2 08/16] checkasm/sw_range_convert: test all supported bit depths

This commit also reduces the number of times ff_sws_init_scale() gets
called (only once per bit depth), and the number of times randomize_buffers()
gets called (only if the function must be checked).
Benchmarks are only performed on bit depths 8 and 16 (since they are
different functions, and not only different constants).
