testsuite: XFAIL some Wstringop-overflow tests ...
... for targets that support vectorization of 2-byte char stores
with unaligned address at plain O2.

gcc/testsuite/ChangeLog:
* lib/target-supports.exp (check_vect_slp_store_usage):
Handle TEST_V2QI_2.
(check_effective_target_vect_slp_v2qi_store_unalign): New procedure.
* c-c++-common/Wstringop-overflow-2.c: XFAIL specific tests for
vect_slp_v2qi_store_unalign targets.
* g++.dg/warn/Wstringop-overflow-3.C: Ditto.
* gcc.dg/Wstringop-overflow-28.c: Ditto.
* gcc.dg/Wstringop-overflow-68.c: Ditto.
* gcc.dg/Wstringop-overflow-75.c: Ditto.
