[BoundsSafety] Unbreak CodeGen tests likely broken by new nocreateundeforpoison attribute

llvm#164809 adds a new attribute
on various intrinsics including `llvm.sadd.with.overflow.i32` which is
used in the two test cases. This patch adds the missing attributes

Matching the attributes in this test is kind
of silly because there's no corresponding use of `#ATTR1` in the test.
If this continues to be a problem we should probably just manually
remove the lines that `update_cc_test_checks.py` added.
