630c8ed1e0 Fix for ScaleDownBy4_Linear_16 
The unittest compares the results of 8 and 16 bit scaling
and expects them to be the same.  This CL makes the 16 bit
scaling filter logic match.

0d880e5bc0 rename MIPS_DSPR2 to DSPR2 for consistency 
When attempting to normalize function names to end in Row_SIMD it was made
harder with MIPS_DSPR2 naming convention.
Other CPUs do not include the vendor.  This should be named consistently.

Removed the DISABLE_MIPS in favour of DISABLE_ASM for consistency with other
processors.

05416e2d9a Box filter for YUV use rows with accumulation buffer for better memory behavior. The old code would do columns accumulated into registers, and then store the result once. This was slow from a memory point of view. The new code does a row of source at a time, updating an accumulation buffer every row. The accumulation buffer is small, and should fit cache. Before each accumulation of N rows, the buffer needs to be reset to zero. If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.

9ed836b154 The 'Any' versions of functions can handle any width now, so remove the check from the calling code. This has 2 advantages - less code, and less overhead in calling function when any function is NOT used. Downside is more code for case where any is used.

ca308327d2 Remove unaligned functions, since most function support unaligned memory now. This reduces complexity and improves performance for unaligned cases because C code can be avoided, and overhead is less. Downside is old cpus (core2 and earlier) will be slower for aligned memory case. Except mips, which has alignment requirement, but remove unaligned variant.
