Add the ability to benchmark YCCK JPEG compression/decompression. This is particularly useful since that is the only way to test the performance of the "plain" upsampling routines, which are accelerated on some platforms.

Ensure that tjFree() is used for any JPEG buffers that might have been dynamically allocated by the compress/transform functions. To keep things simple, we use tjAlloc() for the statically-allocated buffer as well, so that tjFree() can always be used to free the buffer, regardless of whether it was allocated by tjbench or by the TurboJPEG library. This fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag.

Extend tjbenchtest so that it tests the dynamic JPEG buffer allocation feature in TurboJPEG. Disable the tiling feature in TJBench whenever dynamic buffer allocation is enabled (because the tiling feature requires a separate buffer for each tile, using it successfully with dynamic buffer allocation would require a separate TurboJPEG compressor instance for each tile, and it's not worth going to that trouble right now.)

If we have transformed a 4:2:2 or 4:4:0 image in any way that transposes the horizontal and vertical dimensions, then we need to inform the decompression function that the subsampling type has changed. Otherwise, tjDecodeYUV() will not produce correct results.

Since we now have a complete set of YUV functions, TJBench can be greatly simplified. It now tests YUV encoding/decoding as an intermediate step of JPEG compression/decompression, which eliminates the need for a separate YUV mode. Several other things have been streamlined in the process.

Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.
