  [clang][test] Make new absurdly_big_struct test more targeted (#219897)

The previous version of `y()` used `c2[i]`, which can't be evaluated at
compile-time.
The emitted diagnostic depends on something calling
`ASTContext::getASTRecordLayout()` for `b`, which currently happens in
the constant evaluator. If the evaluator decides to evaluate `c2[i]`
before calling `getASTRecordLayout()`, the test fails since the
diagnostic is never emitted.

Fix this by simply using `c2[0]` instead.
