Remove some code in libsvn_delta that assumes unaligned access is safe
and therefore breaks GCC's vectorizer. The new code also attempts to
make better use of the CPU data cache.

* subversion/libsvn_delta/text_delta.c
  (fast_memcpy): Simplify the short copy loop implementation.
  (patterning_copy): Do not blindly use unaligned word-size access.
   Keep the data cache hot when repeating a pattern.
