-Fix a snafu that prevented the optimized code path to be executed in most
-cases. This affects legacy txdelta v1 data only - which is quite rare to
-find these days.
-
-* subversion/libsvn_delta/text_delta.c
-  (patterning_copy): there will be no overlap past the END ..

-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.
