Supplement to PR #144073 Previously, _msan_check_mem_is_initialized.cpp_ initialized a 32-byte stack array, but checked the shadow for the offset range [12, 42), exceeding the stack array size. MSan does not guarantee that the shadow corresponding to the overflow part is 0, so it is undefined to require the overflow part to be unpoisoned.
