Adjust testcase for O2 vect.
Adjust code in check_vect_slp_store_usage to make it an exact
pattern match of the corresponding testcases.
These new target/xfail selectors are added as a temporary solution,
and should be removed after real issue is fixed for Wstringop-overflow.
gcc/ChangeLog:
* doc/sourcebuild.texi (vect_slp_v4qi_store_unalign,
vect_slp_v2hi_store_unalign, vect_slp_v4hi_store_unalign,
vect_slp_v4si_store_unalign): Document efficient target.
