-mstringop-strategy=rep_8byte with -m32.

time even when count_exp was constant forced into register.  For

and invoke the body algorithm.  If need_zero_guard, add zero guard
even if count is non-zero, but smaller than size_needed + number of
bytes that could be stored for alignment.

but smaller than size_needed + number of bytes that could be stored

of desired_align - align, don't adjust size_needed, pass
epilogue_size_needed to the epilogue expanders.
