Reason of this bug is that ARM64 can't extend the sign bit of a 32-bit integer
to 64-bit integer automatically.
ScaleARGBRowDownEven_NEON is also enabled for ARM64.

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.
